Pull request tool call feedback

[Tyriar]

Just saw this happen:

Some notes:

• It's a different style to all other tool calls. It does look close to the exploration in the terminal tool fwiw https://github.com/microsoft/vscode-copilot-release/issues/6283
• It's not clear what it did from just reading the title, should it say Read Pull Request?
• Expanding it shows rather unfriendly content

@roblourens, can we use the pastTenseMessage api proposal? I'd like to do "Reading pull request xyz..." and then "Read pull request xyz...". Additionally, do we have any control over that Input and Output display from an extension?

To verify, use the #activePullRequest tool when you have a PR checked out, and verify that the tool call info is better than it was in the screenshot.
