chore: add .git-blame-ignore-revs (#2366)

Clear some "noise" when using GitHub's "blame view" UI tool to see changes in code history for individual files.

These commits are chosen as they are mostly style-related changes rather than code refactors (minor refactors are OK):

- de38a5b
- 675d12b
- 2912b1d
- 5d4324d
- 16b84e8
- b142b08
