Bug 1835046 [wpt PR 40223] - bidi: remove tlsEnd from network.FetchTimingInfo, a=testonly

Automatic update from web-platform-tests
bidi: remove tlsEnd from network.FetchTimingInfo (#40223)

tlsEnd never made it to the spec:
https://w3c.github.io/webdriver-bidi/#type-network-FetchTimingInfo

c.f. w3c/webdriver-bidi#204:

> tlsEnd: float this should be the same as connectEnd

As it is a redundant param anyway, remove it from WPT.
