Please use the Github API, Gitlab API, Bitbucket API

I saw that the Git is using bash commands.
Please use their official API instead because using bash requires Git configurations and might not matches your git configuration locally with using cloud containers etc.

Github API

https://docs.github.com/en/developers

Github PHP Wrapper

Gitlab API

https://docs.gitlab.com/ee/api/

Gitlab PHP Wrapper

Bitbucket API

https://developer.atlassian.com/server/bitbucket/reference/rest-api/
https://developer.atlassian.com/cloud/bitbucket/rest/intro/ (CLOUD)
https://developer.atlassian.com/server/bitbucket/how-tos/command-line-rest/ (SERVER)

As I see you do Provider checks here so you can make use of which API to use.

You are right

$command = ['git', 'ls-remote', '--heads', 'origin', $this->getHeadBranch()];

Long term the proper API should be used here.

For now in beta phase I think the developers will need to keep the current flow for now, but there are backlog tickets that will address this.
