Cosmetic changelog/changie fixups

[jtcohen6]

resolves #4943

• Reorder change types, both how they'll be ordered in the generated changelog (main concern), and how they'll be presented to contributors for interactive selection
• Reorder v1.1 release notes + changelog accordingly
• Add language to v1.1.0b1 "breaking change" to clarify exactly who this might be breaking for (sorta adapter plugin maintainers, really nobody)
• Contributors: → ### Contributors (feels right)

After merging: Update v1.1.0b1 release notes

This one is a no-look pass, I could be wildly off the mark

It's easy to test all your changes work as expected!

Run this to print out what the generated yaml file will be:

changie batch 1.1.0 --dry-run --include '1.1.0'

--dry-run just prints out what would be generated and doesn't actually create a file or delete any yaml and --include will include the yaml files in that directory.

Note: Two new changes have been merged in since the release (2 files exists in .changes/unreleased) so those will be erroneously included. Since it's not creating the files it doesn't matter. This command should be enough to eyeball that the file is generated like you expect.

realized I needed to update my installed version of changie! after that, works like a charm
