Automatically reset goldy cache after a certain period.

[THEGOLDENPRO]

In goldy bot pancake #113 the framework now caches a multitude of data including, goldy bot repo data and application data.

At the moment cache is pretty much persistent, it doesn't get cleared unless you pass --no-cache to the start command or just delete the file.

This is a problem for data such as repository data, like if a new extension gets added to the repo, goldy bot will not pull it as it's reading outdated cache. So it's clear we need to implement some type of expiring date system in the cache object like so:

{
    "repo_data": {
        "data": {
            ...
        },
        "expires": "1708378072"
    },
    ...
}

Not final design, changes will be made.
