Added template local development docs

[mishushakov]

• Added docs on how to develop templates locally using Docker

[dobrac]

let's describe two use cases of local development we have now:

• start with proper E2B testing/dev workflow, describing how to work with that
• then keep what you have there now, just to add another interesting use case for the build system capabilities

this way, we would

• help you with how do we envision working with the build system
• promote E2B and how easy it's working with it
• still showing you alternative ways that might be really useful

@beran-t any reason this was closed?

[beran-t]

@mishushakov I wanted to clean up old PRs. I was not expecting these PRs to have anything relevant at this point.
I think we would have to review and update all of the examples anyway.

I'll create a better way, probably in Linear, to add/update things in docs.

[mishushakov]

I will reopen this one and put in drafts. Just needed to finish it properly, but I think the doc is still valuable

PR Summary

Low Risk
Documentation and navigation only; no runtime or API code changes.

Overview
Adds a Local Development doc page that explains how to turn E2B Templates into Dockerfiles with Template.toDockerfile() / Template.to_dockerfile(), build images, and run them locally, including TypeScript/Python examples and a Compatibility table of supported vs unsupported template methods.

The page is wired into the Custom sandbox nav in docs.json (between Customization and Examples). README only gains a trailing period on the main heading.

Accidental README title change

Low Severity

The README heading was changed to # Mintlify Starter Kit . with an extra space and period, unrelated to the local development documentation work.
