Default github api url

[FestineOnGCP]

Hi everyone,

I have been using argocd image updater for more than a year now and the product has been great.
Kudos to everyone who has made this a success.

However, I'm trying to use argocd image updater to authenticate with a github application secret. On the logs I see that the github api url is https://api.github.com/app/installations/$MY_INSTALLATION_ID/access_token. How can I change this default github api url to point to a githubAppEnterpriseBaseUrl (that is an enterprise github api url)?

I'll greatly appreciate it if I can get a feedback soon.
Thank you.
