Move jsdoc tag at the end (otherwise it grabs all text)

[swallez]

Fix the body's comment in MultiSearchTemplateRequest: the @codegen_name jsdoc tag was on the first line, which caused it to grab all following lines, which is not exactly what we want 😅

The backport to 8.17 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-8.17 8.17
# Navigate to the new working tree
cd .worktrees/backport-8.17
# Create a new branch
git switch --create backport-3666-to-8.17
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 c9adece35c777c343d29ab3af14825e29f522c88
# Push it to GitHub
git push --set-upstream origin backport-3666-to-8.17
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.17

Then, create a pull request where the base branch is 8.17 and the compare/head branch is backport-3666-to-8.17.
