CI is skipping commits with the word "bump"

[woile]

Goal
Allow execution of auto bump when writing the word "bump" in the commit message.

Description
Currently we are skipping a bump if the message contains the word bump, but it should be skipping if it begins with bump:. see line

Suggestions
Change from
if: "!contains(github.event.head_commit.message, 'bump')"
to
if: "!contains(github.event.head_commit.message, 'bump:')"

This will only skip commits auto-generated because they have a :.

Another option is to is to use the begins with from github actions or something similar
