fix: improve clarity in workflow documentation steps after review

[FidelusAleksander]

Summary

Changes

This pull request makes several improvements to the GitHub Actions workflow documentation for Node.js projects. The changes clarify instructions, improve the formatting of workflow-generated comments, and ensure users are guided to push their changes. These updates help make the workflow setup process more user-friendly and reduce potential confusion.

Documentation and instruction clarity:

• .github/steps/1-step.md: Clarified where to add the workflow content by specifying it should be added to the bottom of the reusable-node-quality.yml workflow file, rather than just the file itself.
• .github/steps/2-step.md: Improved the instruction wording to direct users to add (rather than copy) workflow content, making the process clearer.
• .github/steps/3-step.md: Updated instructions to explicitly tell users to commit and push their ci.yml changes, ensuring the workflow is triggered.

Formatting improvements:

• .github/steps/3-step.md: Enhanced the table formatting in the workflow-generated pull request comment by clarifying column headers and making the table more readable.

Closes:

Task list
