[Feature Request]: Show separate tab for extension pack

[ReinhardKeil]

CMSIS-Debugger 1.3.0

Debugger shows "Extension Pack Info" intermixed with README

---

CSolution extension has a separate tab (which I prefer as README is easier to digest).

[jreineckearm]

VS Code renders based on existence of category "Extension Packs". That is also used by marketplace filtering by category.

Changeable by removing the category from the CMSIS Debugger extension manifest.

Would you like to see the same change for "Arm Keil Studio Pack (MDK v6)"?

[ReinhardKeil]

@jreineckearm Yes, please make it consistent with "CSolution extension" for all our extension packs
