[FIX] website: accept 'all' google console search key

lstrip remove each letter, and not only once in this order.
So a google console key like googleeef88156 will be never trusted.
'googleeef88156'.lstrip('google') = 'f88156' and not 'eef88156'

Now we ensure that it starts with google or ends with .html and remove
exactly what we know.

To replace with removeprefix/removesuffix once we have py3.9 as minimal
version.
