[chemie]: Quite a mess in the WC entries

[TCA-Bot]

So, I've visited every WC in Geb. 5401-5407, and I've discovered that the records in NavigaTUM is quite a mess.

1. Many WC in the records are not gendered. Some even have the wrong gender or category. I've included the gender of the WC in the "Gender sign" column and highlited the errors in red.
2. Some WC in NavigaTUM records either do not exist (marked 404 not found) or are actually other rooms (marked Not a WC!!!)
3. Local number for 5406.02.610L should be 36004, not 36104A

Related #586 => unshure if the spreadsheet changes the mergability of said data and if waiting until I can get #670 fully debugged + shipped is a better call.
