Deployment

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.
GitHub Actions CI will create an artifact under the tag. Download it, sign / notarize the app, and upload the dmg to the release.
