Pester symbols for setup/teardown blocks

[fflaten]

Summary of the new feature / enhancement

Add document symbols for Pester's setup/teardown blocks for outline/navigation-purposes

• BeforeAll
• BeforeEach
• AfterAll
• AfterEach
• BeforeDiscovery

The blocks are unnamed, but outline shows order and nesting so they still make sense.

Proposed technical implementation details (optional)

Only document symbols for outline. No references/definition or code lense.

If this makes sense to support, I can offer to look into it. Feels like I'm getting acquainted with the symbol providers lately 😄

Maybe also InModuleScope <Module>. Not as important, though it would make so much sense with the new experimental vscode sticky scroll which reuse the same symbols.

@nohwnd Thoughts on this (issue as a whole)?

Update: Decided to drop it because we recommend to minimize use of InModuleScope .. and ideally only for parts of code in It-tests. It would just be noisy.

I like it. 🙂
