Runnables, injections and minor improvements

[tigormal]

Foreword

^{Things should probably be better tested. I have noticed some bugs occur at random times, but could not reproduce them, and it could've been on the side of Zed itself too.}

Runnables

Added support for play button in:

1. when isMainModule: sections
2. suite and test macros for unit tests

Unit test runnables support running suites, separate single tests and single test within suites. Works with default unittest and unittest2 modules.

Injections

Fixed language name capture for emits and Assembly, added Markdown injection for md"..." generalized strings.

Before	After

Note:
Zed should have a corresponding language extension installed for syntax highlighting to work: SQL, Assembly, GLSL and others.
As of now (02.11.2024), there is no language extensions for Objective-C, hence there is no syntax highlighting for it. If such extension appears, it in theory should work as-is (if it has objc language ID).

Other stuff

• Added .nims file extension for NimScript files.
• Added auto-close and bracket handling for pragmas (probably not in the best way, but it works)
  

Edit:
Resolves #3.

Also, with the current functionality, maybe it is time to update the version to 0.1.0, and not 0.0.6? A lot of other language extensions do not have runnables support, and other basic features are already there
