fix: unsupported criterion filter (framerate)

This was added to stash in v0.24.0:

stashapp/stash#4161

(internal/stash/gqlschema/local.graphql says "This file was generated.
 Do not edit manually." but I have no idea how it was generated.

 My limited testing of booting up stash-vr and `wget`ing against
 /heresphere seems to yield valid results; ie, the number of videos per
 saved framerate filters matches what is displayed by stash's frontend.
 And, `wget`ing a random scene in these lists does return a scene of the
 given framerate.)
