fix(amazonq): increase polling frequency for bearer token.

[Hweinstock]

Problem

During the bug bash, someone encountered the LSP attempting to use an expired bearer token. I am unable to reproduce the issue, but can speculate at the cause.

We refresh the bearer token on the LSP every 1 minute, but if the token expires, and then a request is made before the next refresh it can fail.

Note: this is a temporary solution until we have LSP auth.

Solution

• double the frequency with which we check the token.
• We still only send the token if it changed, meaning this won't cause noisy request to LSP.

• This pull request implements a feat or fix, so it must include a changelog entry (unless the fix is for an unreleased feature). Review the changelog guidelines.
  • Note: beta or "experiment" features that have active users should announce fixes in the changelog.
  • If this is not a feature or fix, use an appropriate type from the title guidelines. For example, telemetry-only changes should use the telemetry type.

I can't remember if I understood it right, but I thought I read something that said flare will reject the token if the request fails. If thats the case then maybe thats what happened?

Yeah, still unsure what happened in the bug bash since it isn't documented, but this can't hurt. If we can get a detailed report, then I can dig deeper on the Flare side.
