Merge #7577

7577: Update references to old repo location r=deivid-rodriguez a=duckinator

Related: #7572.

### What was the end-user problem that led to this PR?

A lot of things use the outdated `https://github.com/bundler/bundler` URL (and similarly for e.g. `bundler/bundler-site`).

### What is your fix for the problem, implemented in this PR?

My fix was to update the outdated URLs. :slightly_smiling_face: 

### TODO

- [x] `bundler.gemspec`
- [x] `CHANGELOG.md` (Moved to its own PR, #7582)
- [x] `CODE_OF_CONDUCT.md`
- [x] `doc/`, excluding reference to now-dead `pullreview.com`
- [x] `doc/contributing/HOW_YOU_CAN_HELP.md` reference to long-dead `pullreview.com`
- [x] `.github/config.yml`
- [x] `lib/` (comments)
- [ ] `lib/` (functional changes)
- [ ] `man/`
- [x] `README.md`
- [x] `spec/` (comments, `skip` messages)
