Chat Participant: Syntax tool is not aware of what is supported

[benibenj]

Testing #6331

Prompt: @githubpr How many issues are assigned to both me and alexr00

I don't believe it is possible to create such a query, but the tool does not seem to be aware of it as it created: repo:microsoft/vscode is:issue assignee:@me assignee:alexr00 sort:updated.

[alexr00]

Seems legit to me, but the results are wrong.

When the link has a query embedded with multiple assignees, GitHub removes all except the last one. I would assume this also happens with the API call.

https://github.com/issues/?q=repo%3Amicrosoft%2Fvscode%20is%3Aissue%20assignee%3Aalexr00%20assignee%3A%40me%20sort%3Aupdated
