Command used with act

gh act -W print_context.yml  -j print-context-and-exit

Describe issue

git@github.com:/sh41/act.git is a valid remote in git, but it is not parsed correctly by act. See https://stackoverflow.com/a/70330178 for a discussion of the origins of this syntax.

In the log output you can see:

| GITHUB_REPOSITORY=/sh41/act
| GITHUB_REPOSITORY_OWNER=

which should be:

| GITHUB_REPOSITORY=act
| GITHUB_REPOSITORY_OWNER=sh41

Additional information

I think this can be fixed by changing this line:
https://github.com/nektos/act/blame/3d71542867d7cbdac6a75e540be6f64362e94de2/pkg/common/git/git.go#L29

to:

	githubSSHRegex      = regexp.MustCompile(`github.com(?::/?|/)(.+)/(.+?)(?:.git)?$`)

and for GHE:
https://github.com/nektos/act/blame/3d71542867d7cbdac6a75e540be6f64362e94de2/pkg/common/git/git.go#L212
to

		gheSSHRegex := regexp.MustCompile(fmt.Sprintf(`%s(?::/?|/)/(.+?)(?:.git)?$`, githubInstance))

In both cases

[:/] = either a : or a /
is replaced by:
(?::/?|/) = non-capturing group of either a : optionally followed by a / OR just / on it's own.
