update: fix the flaky table resize test in collab mode

added a fix for the flaky table resize test in collab mode. sometimes, the height is 87px, sometimes it is 88 px.

using the actual html modification call back introduced in https://github.com/facebook/lexical/pull/6240/commits, accept either 88 or 87 px as html output

Closes #6241
