fix: cody://repository isn't able to resolve in cody chat

Fixes SRCH-1592

Currently only for cody://repository. Other fields might be affected, too. Will check for them if the approach taken here is okay.

Test plan

Manual testing, it works now:

I approve because I don't think it breaks anything, but I'm not sure that I understand how it was broken in the first place. The initial context is used in prompt hydration only in the case of Cody Web, VSCode and JB clients should mock their VSCode-like API so we get context info from that API and not context.initialContext.

I was only able to debug via Cody Web, and assumed that JB/VSCode would take a similar approach. Could you help point me to the place where that behavior diverges?

Just tested this again with local VSCode, and it doesn't work at all :(
