Themeing support

[karthik2804]

Added ability to add themes by pulling in git submodules to a themes/ folder as per discussion on #73. The themes can be configured using config/site.toml. Added documentation as well but would definitely need to be proofread.

Any thoughts/suggestions would be appreciated.

Thanks!

Quick question: why are the static files from the docs directory moved to docs/themes/?
I would expect that, if we refactor the current templates into an actual theme, that would be a separate PR.

[karthik2804]

They were just moved there to document and test it as a theme. I could move them back to the original location along with the failing test.

In general, we want to change as few files as necessary as part of a PR.

Thanks!

This is super cool!

I was also wondering which section the documentation will follow in the existing documentation so that I can add the proper links to the site to maintain the chaining of secitons.

This looks great. Just a handful of typo/grammar suggestions. Looks like the bartholomew.wasm file needs to be updated as well after the recent merge. Thank you!

@vdice I will resolve the conflict along with the fixes and push a new commit. I had one question as to where the docs for themes must be listed.

The current order of sections is

1. Introduction
2. Quickstart
3. Templates
4. Configuration
5. Scripting
6. Markdown guide

I am not sure where the "themes" section fits in that order.

@karthik2804 good question. No strong opinion here; I think the current ordering in this PR of 4. Configuration 5. Themes 6. Scripting (and so on) makes sense. We'll want to update the end sections accordingly, eg update https://github.com/fermyon/bartholomew/blob/main/docs/content/configuration.md?plain=1#L40 to navigate to the new Themes section and then at the end of the Themes doc we can link to the Scripting page.

LGTM!
