Add spelling correction for siver->silver/sliver/diver

[cfi-gb]

See e.g. https://grep.app/search?q=siver&words=true

Note: There are names like "Kay Siver" but also various typos like e.g. the ones below so hope it is correct to add it like this.

Don't worry, any typo could be a name (of a person, of a place, of a fictive character or place). We wouldn't have a dictionary of possible typos if we were to take that into account.

Perhaps add diver?

Thanks a lot for the additional opinion about the names and similar, sounds absolutely reasonable to handle it like this 👍

I have also added diver as well, sounds absolutely valid.
