Redirect project docs url with improper capitalization and trailing slash

[mszell]

Currently, https://docs.bikenetkit.org/growbikenet correctly redirects to https://docs.bikenetkit.org/GrowBikeNet/, but https://docs.bikenetkit.org/growbikenet/ gets stuck at the 404 page. It should also redirect to https://docs.bikenetkit.org/GrowBikeNet/

Note that for some reason, the first link above does not get redirected, only once the URL is confirmed with press of enter. Anyway, this is very low priority.
