Revert "Adds translattion of highlight annotations"

This reverts commit 0107f80

The reason for doing this is explained by @Vizs in vedang#143, copying the
message here:

Andreas wrote the function
`annotation_translate_quadrilateral`[^1][^2] to fix misplaced
annotations due to the then bug in `glib`. This misplacement bug can
be seen in the images posted in issue politza/pdf-tools#577, along
with PDFs in which the bug can be reproduced.

This lack of translation in the `glib` backend was fixed in `poppler
0.86.0` but the workaround was still left hanging in `epdfinfo.c`
which brings us to today where this unneeded translation bites our
back. I commented out the calls to
`annotation_translate_quadrilateral` in `epdinfo.c` and to my
surprise, there were no misplaced translations in files which
displayed the misplacing behaviour and in files which did not have
this behaviour.
