[WIP] chore: Add workflow files

[ebebbington]

Adds workflow files for:

• ci - running tests (incl bson), format check and lint check
  • Could be done for bson as well? (rust fmt check)
• bumper - bumps Deno and Rust dependencies
  • To be decided which module manager to use
• release - Releases to eggs.land on publish

This is a work in progress, and also a proposal.

Things left to decide are:

• Which MM to use (./.github/workflows/bumper.yml)
• Running of tests needs to be added (.github/workflows/ci.yml)
• CI_TOKEN needs to be created to allow pushing
• NEST_LAND_API_KEY token needs to be created for pulishing to nest.land

Suggestions/improvements/questions are obviously welcome. This PR is subject to change based on peoples opinions and further developments

master - running tests (incl bson), format check and lint check

Can we rename this to ci.yml?

Done

Also feel free to push to this PR too if needed (same goes for @Qu4k)

Will definitely need some input on the Rust CI (maybe wasm too?) stuff whenever, as that's not my 'territory'
