feat: improving the bump script

[sabify]

Related: #4172

The script now detects if any changes were made to a member from a commit release up to the latest tag.

@gbj, if you are going to release and publish a member crate without releasing a tag, please push a commit in the following format to keep track of the changes: <member-name>-v<member-version>. For example, oco_ref-v0.2.1.

Please keep in mind to use the member package name defined in the Cargo.toml, not the directory name.

Here is the logic:

• If there is a release commit newer than the latest tag for the member crate, check if there are any changes made to it from the release commit and request a bump.
• Otherwise, use the latest tag and check if there are any changes made to the member crate and request a bump.
