ci: skip 'update-cli-screenshots' if no changes

[marcosdotme]

Description

Job update-cli-screenshots was failling when no changes detected on docs/images/cli_help and blocking other jobs to run.

Closes: #1138

• Run ./scripts/format and ./scripts/test locally to ensure this change passes linter check and test
• Test the changes on the local machine manually

Expected behavior

Job update-cli-screenshots must be skipped if no changes detected on docs/images/cli_help

Overview

Explanation

I made two commits:

1. Commit with no changes related to CLI, so theres no changes detected from update-cli-screenshots (114383c).
2. Commit with changes on CLI (changed description of commands) (b585baf).

Note that commit with no changes exits with status 0 and don't creates the commit "docs(cli/screenshots): update CLI screenshots"

The code looks good. But we'll have to change the commit message type to ci instead of fix.
