Make logging more friendly for docker

Prerequisites

• I have added steps to test this contribution in the description below

Description

With docker in mind, this PR sets out to make it easier to change the default logging behaviour shipped with Umbraco by

• Making it possible to disable the UmbracoFile sink through configuration so no files are written to disk
• Make it easier to overwrite the new logging services introduced in v14+
• Supplying updated documentation: Update logging with new abstraction/configuration UmbracoDocs#7271

Testing

• Try to disable the UmbracoFile sink and verify no files are written to disk
• Test the abstractions by setting up a custom implementation of the newly added base classes. Example can be found in Update logging with new abstraction/configuration UmbracoDocs#7271

I've tested out the two scenarios.

Disabling the UmbracoFille sync in configuration prevents logging.

I could setup a custom log viewer source with the following:

using Umbraco.Cms.Core;
using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.Logging.Viewer;
using Umbraco.Cms.Core.Persistence.Repositories;
using Umbraco.Cms.Core.Scoping;
using Umbraco.Cms.Core.Services;
using Umbraco.Cms.Core.Services.OperationStatus;
using Umbraco.Cms.Infrastructure.Logging.Serilog;
using Umbraco.Cms.Infrastructure.Services.Implement;

public class LogViewerComposer : IComposer
{
    public void Compose(IUmbracoBuilder builder)
    {
        builder.Services.AddUnique<ILogViewerService, CustomLogViewerService>();
        builder.Services.AddUnique<ILogViewerRepository, CustomLogViewerRepository>();
    }
}

public class CustomLogViewerRepository : LogViewerRepositoryBase
{
    public CustomLogViewerRepository(UmbracoFileConfiguration umbracoFileConfig)
        : base(umbracoFileConfig)
    {
    }

    protected override IEnumerable<ILogEntry> GetLogs(LogTimePeriod logTimePeriod, ILogFilter logFilter)
    {
        return new List<LogEntry>
        {
            new LogEntry
            {
                Level = Core.Logging.LogLevel.Information,
                MessageTemplateText = "This is a custom log entry: {Foo}",
                RenderedMessage = "This is a custom log entry: Bar",
                Timestamp = DateTime.UtcNow,
                Exception = null,
                Properties = new Dictionary<string, string?>
                    {
                        { "Foo", "Bar" },
                        { "MachineName", "MyServer" }
                    }.AsReadOnly()
            }
        };
    }
}

public class CustomLogViewerService : LogViewerServiceBase
{
    public CustomLogViewerService(
        ILogViewerQueryRepository logViewerQueryRepository,
        ICoreScopeProvider provider,
        ILogViewerRepository logViewerRepository)
        : base(
            logViewerQueryRepository,
            provider,
            logViewerRepository)
    {
    }

    protected override string RepositoryLoggerName => "MyLogger";

    public override Task<Attempt<bool, LogViewerOperationStatus>> CanViewLogsAsync(LogTimePeriod logTimePeriod)
        => Task.FromResult(Attempt.SucceedWithStatus(LogViewerOperationStatus.Success, true));
}

As noted on the docs PR, I created an implementation of the service too. This wasn't necessary, but I think it's better to have otherwise there's some unnecessary attempts to read files from disk in the CanReadLogs method of the default implementation.
