Deploy

Update src/MacVim/Info.plist CFBundleVersion to NUMBER.
Commit src/MacVim/Info.plist with meaningful commit log like this and push it.
Create a signed annotated snapshot-NUMBER tag (make sure you have Git set up to sign, and the signature is registered at Github) and push the tag to the origin.
```
 $ git tag -a -s snapshot-NUMBER
 $ git push origin snapshot-NUMBER
```
- Don't use git push origin --tags!
Go to the Tags page and find the tag you made and create a release out of it. Choose a title similar to previous releases (e.g. "MacVim Snapshot 155"), and paste in the commit message to the descriptions. Clean up the message and add screenshots / videos as needed to make it look good. Wrap the "Compatibility" section under a <details><summary>Compatibility</summary> ... </details> block so they don't waste space.
GitHub Actions CI will create an artifact under the tag. Download it, sign / notarize the app, and upload the dmg to the release.
