Update tutorials

[C-D-Lewis]

Goes some way to fixing #44 by testing creating projects from the snippets, and fixing dead links and small errors in code.

Also includes full source-code files as an expandable at the end instead of relying on a third-party Gist.

• Fix way outdated mobile nav
• C tutorial
• JS tutorial
• Advanced tutorials? Requires missing example files (PDC SVG Zip file)

@Sorixelle Seems GitHub's auto-merge main feature doesn't add the signed off by. Is that still an issue?

@Sorixelle De-scoping the "Advanced Tutorials" section that contains only the PDC tutorial because it requires some files that I can't find anymore - broken link to the Pebble S3. It can be done in a follow-up PR.

It is annoying but the checks don't like it, yeah. Generally, prefer rebases over merging to update a branch - it doesn't create an extra commit.

Sorry it's taken me so long to get to this one - gotta find time to properly look through the changes.

Gotcha, I'll update it soon. Thanks for your review! No problem 😄

@Sorixelle Things seem happier now!

[C-D-Lewis]

@Sorixelle Fixed lint error! Good to merge now I think!

[Sorixelle]

Whew, sorry for taking so, so long to get around to this one. It's looking good, and I'm not fundamentally opposed to the changes. There's a few bits that need some cleanup though, I've left a handful of comments.

[C-D-Lewis]

@Sorixelle Addressed the suggested changes or otherwise left comments in response. Please take a look again when able!

[C-D-Lewis]

@Sorixelle Ready to land! Thanks for looking at this one :)

[Sorixelle]

Just one tiny nitpick left, then we should be good to go!

[Sorixelle]

Thanks for taking this one on!
