Bug 2001678 [wpt PR 56188] - [Prompt API WPTs] Fix Language Model QuotaExceededError test, a=testonly

Automatic update from web-platform-tests
[Prompt API WPTs] Fix Language Model QuotaExceededError test

The test now allows for a small delta when comparing the 'requested'
value in QuotaExceededError, accommodating potential minor variations in
token counting.
