fix: Upgrade version of jwt-go package to v4.0.0 (influxdata#19893)

* fix: Upgrade version of jwt-go package to v4.0.0

This commit updates the dependencies for influxdb to require v4.0.0-preview1 of
the jwt-go package.  This required updating the go.mod and go.sum files as well
as any source file that directly imported that package.

Prior to this commit, the TestHandler_Query_Auth() tests would fail as it
checked for specific error strigns returned by the jwt-go package.

Version 4.0.0-preview1 of the package changed the verbiage of those errors a
bit.  This patch updates the test to detect the new error string.
