Standardize frontmatter across Tutorials

[yvonnefroehlich]

Related to #1 (comment), this PR aims to standardize the frontmatter across the tutorials:

• Mention pre-workshop (Jupyter book, GitHub, AGU Session)
• History (author, creation date, recommended versions)
• Consistent titles, also with intro page (if you don't like to have emojis in your tutorial, just comment on this 🙂)
• Links to the PyGMT documentation
• Mention the GitHub repo for errors and the GMT forum for questions
• Make headings consistent - Please check for your tutorial if that the structure of headings is correct!

This is great! I pushed a couple small changes rather than providing a review given the limited time remaining. Thank you for these improvements!

@yvonnefroehlich are you planning to make any more changes to this? It'd be great to merge if not

No worries! This is totally fine. And thanks for doing the rst related stuff 🙂.

At the moment I will not work on this. So, feel free to merge this PR. Then people can continue with other PRs (code linting etc.).
