Change references of "master" to "main"

[antazoey]

Docs Request

Change all instances of master to main in the docs and and examples.

Reasons

• main is the default
• Many repos changed their default from master to main.
• It is an opportunity to refreshen up the docs.

Keep my forks updated from where I've forked. If I've forked from the master, get from the master. If I've forked from the main, get from the main.

I also feel that the default settings must check the main branch of the fork. Not all repos changed from master to main.

As an organization we have decided to fork all the GitHub actions used. Adding a config file to them is a huge overhead.

Hey @mazilu88 pull does check and use the default branch automatically.

[mazilu88]

You are right. I went through the audit log and found repos with master and main being updated.

Does the App triggers only when new changes are made in upstream after the App was installed?

Because I have some repos that haven't been synced and I think that may be the reason.

@mazilu88 should still work please open a separate issue as it's unrelated.
