Add pre-commit script to keep tags sorted in OpenAPI spec

[pankajkoti]

Following up with PR #38717, this PR adds a pre-commit hook
to keep the tags list sorted in the OpenAPI spec yaml.

I previously tried to use the pyyaml library, to find the tags
and rewrite sorted tags, but upon rewrite it does not maintain
the original order of components in the YAML thus creating
huge changes for the PR to review. Hence, taking a simple
approach to read the file line by line, find the indexes of the
start entry and end entry of the tags list, sort those specific lines
and rewrite the lines with the sorted list of tags.

Yeah. Sometimes parsers are not the best in preserving thigns and old-good file reading + regexp is best.
