[BUGFIX] Add maxwidth / maxheight parameters to YouTube oembed url

When uploading new assets to the filelist,
the metadata (e.g. width and height) are
automatically extracted from the corresponding
files. This does not work for online media files,
e.g. a YouTube video. Therefore, the corresponding
services' oembed API is used to retrieve the
related metadata.

YouTube however changed their oembed API recently
to always set a width of "200" and a height of "113"
by default. This is obviously far too small for any
use case.

Since YouTube is following the oembed specification
(https://oembed.com/#section2.2), it's possible to
provide the "maxwidth" and "maxheight" parameters
to the oembed URL. This way YouTube returns
meaningful values for width and height.

Actually a similar change was already done to
the Vimeo integration in #85176. Vimeo however
supports the custom "width" parameter, which is
not mentioned in the specification and also not
supported by YouTube.
