Rename automated commit messages to be more meaningful

[izmalk]

Problem to Solve

If we push to the docs repo, the web-docs repo will have automatic commit to update its submodule. For example, 2b5109b

The message for the automated commit might be clearer.

Current Workaround

//ci:release-docs: typedb/typedb-docs@8bcb2b4

Proposed Solution

We can use the commit message from the docs repo to make a more meaningful commit message here.

For example:

//ci: {first few symbols of the docs commit message} typedb/typedb-docs@8bcb2b4

or for the exact commit message of the commit above -

//ci: Minor update typedb/typedb-docs@8bcb2b4

Additional Information

This affects how we see the deployment in the Netlify:
