Separate testcontainers and modules into workspaces and publish as distinct packages into the testcontainers NPM organisation

[cristianrgreco]

WHAT

Restructure the project to use NPM workspaces.

WHY

1. Currently installing testcontainers downloads files and dependencies for all modules, which is unnecessary.
2. Separating out testcontainers into its own module makes it easier to create new modules.

HOW

Split the testcontainers core project into its own workspace. Split each module into its own workspace. Publish the packages to the testcontainers NPM organisation following this structure:

testcontainers
@testcontainers/<module>

https://www.npmjs.com/search?q=%40testcontainers

Users can now install just the module they need:

npm install @testcontainers/postgresql

Considering this is a breaking change, this will include 2 other breaking changes:

1. Remove deprecated lifecycle callbacks #525
2. Add static helper for pull policy #524
