Fix extension README command table to match actual commands

[adamint]

Description

The extension README command table was out of sync with the actual commands registered in package.nls.json. This updates it to be consistent.

Changes:

• Renamed commands to match their actual titles:
  • "Configure launch.json" → "Configure launch.json file"
  • "Manage configuration settings" → "Extension settings"
• Added missing commands that were in package.nls.json but not in the README:
  • "Initialize Aspire"
  • "Open local Aspire settings"
  • "Open global Aspire settings"
• Removed the "Availability" column — the "Available"/"Preview" distinction was not reflected in the codebase and was outdated.

Fixes #14425
