chore(tui): remove unused experimental keys

[IdrisGit]

What does this PR do?

cleanup a couple of experimental keys (hook and chatMaxRetries) from the config that are not used anywhere.

How did you verify your code works?

1. grepped through the codebase to find if these keys are used anywhere
2. the typecheck would have failed after generating new type gen, if they were used anywhere in the codebase but it didn't fail (screen record below).

@rekram1-node can you please help me with the issue (screenshot below)

is it an issue with the workflow or do I need update some settings in my fork? because the generate step runs fine, it's the commit and push which is failing.

Also I am confused, why does the action need to push changes to my fork?

I am guessing it's an artifact of the workflow being run during release earlier but now it's added to the PR?
