Use silverstripe/supported-modules

[emteknetnz]

Currently rhino runs off a hardcoded list for the modules it pulls information for

This isn't great because it includes some unsupported modules in the builds list and we waste time remedying them

It should instead use silverstripe/supported-modules

Note that silverstripe/supported-modules doesn't list some repositories we care about such as the gha* repositories. Either they should be added to the supported-modules JSON, or we need to keep them hardcoded here. - That's no longer relevant as of #17

Acceptance criteria

• Rhino is updated to fetch supported modules from silverstripe/supported-modules repo
• Rhino honours considers the difference in support levels between CMS 4 and CMS 5.
• confluence docs about setting up new repos doesn't explicitly mention Rhino, since that's covered by supported-modules.
  • Note that the version of the supported modules repo we'll get will be locked into the composer.lock file... maybe update these docs to run composer update silverstripe/supported-modules in rhino and redeploy it.

There's a // remove any < 4 minor and major branches for linkfield hack in there right now which can be removed once we're doing this, since linkfield only has one supported branch.

Note that we will need to add a 6 branch to the supported modules repo to avoid a regression of #12

We should keep things silverstripe/cwp-search where there was a CMS 5 unsupported version released in the CMS 4 builds but exclude them from the CMS 5 builds
