Should we add the schema-no-generics.json to our .gitignore?

[sethmlarson]

If output/schema/schema-no-generics.json is removed then we should be good to go.

[swallez]

Good catch with schema-no-generics.json. Added to .gitignore.

The backport to 7.17 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-7.17 7.17
# Navigate to the new working tree
cd .worktrees/backport-7.17
# Create a new branch
git switch --create backport-1773-to-7.17
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick --mainline 1 81791d0a76ad60b997a42e782a25d39a7b5b2363
# Push it to GitHub
git push --set-upstream origin backport-1773-to-7.17
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-7.17

Then, create a pull request where the base branch is 7.17 and the compare/head branch is backport-1773-to-7.17.
