Revert "feat: Add experimental commit message generator (#2306)" (#3161)

This reverts commit 80dbffa.

Context:
https://sourcegraph.slack.com/archives/C05AGQYD528/p1707861341879059?thread_ts=1707832350.281989&cid=C05AGQYD528

Unfortunately, the API used by the feature has been removed from VS Code
and no longer works in the stable version of VS Code:
- microsoft/vscode#200012
-
https://github.com/microsoft/vscode/blob/a776d5fe0a401a0b7dc3b58f28eef1887ad0c15e/extensions/git/src/api/api1.ts#L348-L353

cc @RXminuS we will add it back once the API has become publicly
available again!

## Test plan

<!-- Required. See
https://sourcegraph.com/docs/dev/background-information/testing_principles.
