Increase Sanitization filter timeout

What does this MR do and why?

We added a timeout to our Banzai pipeline. Currently the Sanitization filter is using the default of 2 seconds. If this timer pops, we display a Rendering aborted due to complexity issues. message and halt rendering.

Several folks have hit this timeout, see #469683 (closed). Looks like for now 2 seconds is too aggressive. Bumping to 5 seconds, the same value of the entire pipeline. This should provide additional breathing room.
