What does does this PR do / why we need it:

Update devfile library version

This PR updates the version of github.com/devfile/library/v2 to v2.2.1. One of the new features of library, will let us accept two different components using the same port. This way we can introduce new sample versions that will have consistent ports (using 8080 port).

With the current version of library the registry build fails as the validation of the devfile fails because of using twice the same port for different components. Trace:

* devfile contains multiple containers with same endpoint targetPort: 8080, imported from
id: go, registryURL: https://registry.devfile.io

Use git.revision instead of git.checkoutFrom.revision

The PR also uses replaces the usage of git.checkoutFrom.revision inside the cache_samples.sh by using the git.revision which is the correct field according the Git schema: https://github.com/devfile/registry-support/blob/main/index/generator/schema/schema.go#L224

is this change mean to be pushed?

[thepetk]

Yes, the test was failing due to the previous link. It seems that due to recent changes the URI of this format is not supported anymore. The reason is we are now using DownloadGitRepoResources which expects a git provider link instead of the registry one.
