📦 Add myst-execute package

[fwkoch]

This just adds a basic skeleton package for myst-execute - a sandbox for the jupyter execution work introduced in #856

@agoose77 - hopefully this helps get you started. Let me know if you run into problems or need a hand with anything...

@rowanc1 - I published to npm, ebp-bot should have an invite to enable CI publishing.

[rowanc1]

ebp-bot has been added so CI + deployment should work for this!

[agoose77]

This maybe should return SessionManager, but I don't have a feel for MyST's error handling yet, so erring on the side of "report this in the transform".

[rowanc1]

Any error handling should be done through fileError and fileWarning and passing around a vfile.

Something like:
https://github.com/executablebooks/mystjs/blob/main/packages/myst-cli/src/transforms/code.ts#L159

This will likely also be adding a new RuleId to keep track of these for later processing/ignoring/filtering.

[rowanc1]

Taking another look through!

Looks like there is a merge conflict with the myst-common package and package.json after the release, we might need to rebase and just recommit the package-lock? Let me know if you need help!

[rowanc1]

Thanks for fixing this up @agoose77 -- do you think it is a state that it is ready to come in?

[agoose77]

Just want to tackle a few things RE cleanup first!

[agoose77]

@rowanc1 I removed the logging statements that were expected anyway --- this is good to go imo.

Sorry to be slow hitting merge on this - it looks great! Nice to have a clean, separate package we can start pulling into the CLI.
