Docs: Fix detected misspellings (for first-time contributors only)

Note: these issues are only available for first-time community contributors to GitLab as a tutorial for learning the contribution process, thanks!

Summary

There are a number of detected misspellings in files under the GitLab Docs.

As a practice exercise for first-time contributors, you can follow the steps in this issue to create a merge request and contribute a fix for one of these misspellings:

• You must be a first-time contributor to GitLab
• Please make only one misspelling change per person, even if there are multiple misspellings in the same doc

1. Visit the spreadsheet that tracks these misspellings: https://docs.google.com/spreadsheets/d/1z6NX847wCIeRYeYusNAsZG3X7iM-XHB7QCp9uXbnVSU/edit?usp=sharing
2. Choose one of the misspellings and add your GitLab username in column F
3. Find the file under the GitLab Docs (https://gitlab.com/gitlab-org/gitlab/-/tree/master/doc)
4. Update the code to fix the misspelling
5. Create a merge request
6. Include a link to this issue in your merge request description
