Rename main branch to `main`?

What do y'all think? Plz no trolls

Maybe we can run https://github.com/mheap/github-default-branch for the entire http-rs org?

Yep, let's do it! I believe GitHub will soon release tools to make this transition easy, but if folks want to move ahead before that we can as well!

Yeah I was thinking about this as well, I don't have any objections.

Though I do wish github had chosen "trunk", oh well.

I can do this tomorrow. We'll also need to update a bunch of references to the branch name, but it looks like that's just in readmes and not in things like action configs, so not super high stakes stuff.

One potentially annoying thing for end users is that Cargo uses the master branch for git dependencies by default regardless of what we configure in Github. So if folks are doing things like surf = { git = "https://github.com/http-rs/surf.git" } that will break.
Then again if you're depending on a branch and not a particular commit you can expect to get breaking changes without warning, and this is just one of them 😇

Cargo should tbh probably be patched so that it uses the remote HEAD, tbh. That seems like a pretty bad Cargo bug.

[goto-bus-stop]

It looks like that behaviour was recently changed: rust-lang/cargo#8364
So maybe what I said isn't true anymore? I'm not sure if that PR is in a Rust release already.
