Consider using a monorepo for all python-proton-vpn-* packages

[elenapan]

According to the ProtonVPN/python-proton-vpn-api-core README:

• {GITLAB_INSTANCE} should be set to gitlab.protontech.ch
• {GROUP_ID}should be set to 777

The command then becomes:

pip config set global.index-url https://__token__:{GITLAB_TOKEN}@gitlab.protontech.ch/api/v4/groups/777/-/packages/pypi/simple

However, I get a few errors when trying it:

...
WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f8c4c59e0d0>, 'Connection to gitlab.protontech.ch timed out.

INFO: pip is looking at multiple versions of proton-vpn-gtk-app to determine which version is compatible with other requirements. This could take a while.
ERROR: Could not find a version that satisfies the requirement proton-vpn-api-core (from proton-vpn-gtk-app) (from versions: none)
ERROR: No matching distribution found for proton-vpn-api-core

Maybe this repo's README could be updated to include the correct information?
