Subject: [PATCH 2/5] refactor!: rename FMIndexIndexDetails to FMIndexDetails
 (#7397)

I'm not sure if the original naming was intentional or not. However, it
required a special case in `get_plugin_name_from_details_name` to rename
`fmindex` to `fm` so I'm guessing it was accidental?

We are trying to convert indexes to be "generic plugins" and this means
we cannot have special cases lying around.

An index's short-name is the name of the type URL minus the suffix
`IndexDetails`. So if we want `fm` then it should be `FmIndexDetails`
(which this PR implements). If we want `fmindex` then it should be
`FmIndexIndexDetails` (which it had before). If we want both then we
should invent some kind of formal alias mechanism where an index plugin
can register potential aliases. However, I think it'd be simplest to
avoid that.

This change would be a breaking change to any existing FM indexes! That
index type has not (AFAIK) been formally released yet so I think this is
ok. However, if this misses the 8.0.0 release then we will probably need
to find a different way (and possibly forever be locked into carrying
around this special case).
