Deprecate local param in indices.get_mapping

[pquentin]

This was deprecated in 7.8, but we don't copy this information from the JSON spec, which is a bug.

The backport to 8.16 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-8.16 8.16
# Navigate to the new working tree
cd .worktrees/backport-8.16
# Create a new branch
git switch --create backport-3975-to-8.16
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 ea991724f4dd4f90c496eff547d3cc2e6529f509
# Push it to GitHub
git push --set-upstream origin backport-3975-to-8.16
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.16

Then, create a pull request where the base branch is 8.16 and the compare/head branch is backport-3975-to-8.16.

Unfortunately, the PR you linked that deprecated this parameter in rest-api-spec was incorrect - see elastic/elasticsearch#122922 for more context. The local param was deprecated in elastic/elasticsearch#55014 for the GET field mapping request, not the GET mapping request. I see the local param is not present in https://github.com/elastic/elasticsearch-specification/blob/31b8bb299cf705d9c963a2dfb736c603f47c2425/specification/indices/get_field_mapping/IndicesGetFieldMappingRequest.ts, so we don't have to do anything there. But field should be removed from this line and 7.8.0 should be either removed or updated to 9.1.0 - I implemented the actual deprecation in https://github.com/elastic/elasticsearch/pull/122921/files#diff-759c8fb59bd55bbebf840f520608fabbbc549918cd9121ed754cb629ce5c86c1.
