mount: fix grammar and typo in X-mount.idmap documentation

Apply grammar improvements from PR #4400 (field order change
intentionally omitted as the current order matches the code).
Also fix a GUID -> GID typo in the example.

+An idmapped mount allows the ownership of all files located under a mount to be changed according to the ID-mapping associated with a user namespace.

 The individual ID mappings must be separated by spaces. Please note that in the __/etc/fstab__ file, spaces are interpreted as separators between fields. To avoid this, you must escape them using \040. For example, X-mount.idmap=0:0:1\040500:1000:1.

 For example, the ID-mapping *X-mount.idmap=u:1000:0:1 g:1001:1:2 5000:1000:2* creates an idmapped mount where
