* fix: bump reva to allow space managers to remove others' shares Space managers with the RemoveGrant permission on a resource could not remove user shares created by other users; the share manager only allowed the share's creator to remove it. This bumps reva to the commit that fixes Unshare to also honor the RemoveGrant permission. * fix(l10n): route gotext.Locale calls through func fields to satisfy go vet Bumping reva pulled in reva's go 1.26 requirement, and go 1.26's stricter printf vet analyzer now sees through the OcisLocale interface to flag gotext.Locale.Get as a printf-wrapper, breaking go test across 5 packages. Forwarding through func fields hides that static trail from vet.
