Add a script to update gz dependencies in MODULE.bazel files

[iche033]

Motivation:

When doing a major release, the gz deps in the MODULE.bazel need to be updated to point to the new release branches created in each gz repo, e.g. in gazebosim/gz-sensors#551. This needs to be done in all gz repos. It'll help to have a script to automate this.

One option is to do this by looking at the the collection-*.yaml file to get all expected gz dep versions.

Example usage:

# ./update_bzl_module_deps.bash <release_version> [optional_path_to_module_file]
./update_bzl_module_deps.bash jetty

there are some other configurations currently distributed in each repository that could benefit from scripts like this, most prominent in my mind are the versions / branches used for github actions:

• actions/checkout version (e.g. actions/checkout@v2 is deprecated, replace with v3 #862, CI workflow: use checkout v3 gazebosim/gz-math#519)
• Ubuntu version used with gazebo-tooling/action-gz-ci (e.g. Enable 24.04 CI on harmonic gazebosim/gz-math#590)
• versions of GitHub project automation actions (e.g. Fix Github project automation for new project board gazebosim/gz-math#543)

the bump_dependency.bash script could serve as a reference since it has code to clone all gazebosim repositories, make changes and create pull requests using gh

For the actions/checkout and other third-party github actions we can consider using dependabot.
