feat: Run PreValidate hooks for check cmd (#437)

PreValidate can be used to mount remote directories (e.g. via NFS) so
they must executed first before running any restic commands.

This was done for the backup command in 13aa560, but not for check. This
commit fixes that.

+# 💽 Backends
+
+Backends are the outputs of the backup process. Each location needs at least one.

+Note: names of backends MUST be lower case!

+```yaml | .autorestic.yml
+version: 2
+
+backends:

+```
+
+## Types
+
+We restic supports multiple types of backends. See the [full list](/backend/available) for details.
+
+## Avoid Generating Keys
+
+By default, `autorestic` will generate a key for every backend if none is defined. This is done by updating your config file with the key.
+
+In cases where you want to provide the key yourself, you can ensure that `autorestic` doesn't accidentally generate one for you by setting `requireKey: true`.
+
+Example:
+
+```yaml | .autorestic.yml
+version: 2
+
+backends:
+  foo:
+    type: local
+    path: /data/my/backups
+    # Alternatively, you can set the key through the `AUTORESTIC_FOO_RESTIC_PASSWORD` environment variable.
+    key: ... your key here ...
+    requireKey: true
+```
+
+With this setting, if a key is missing, `autorestic` will crash instead of generating a new key and updating your config file.

+# Copy
+
+Instead of specifying multiple `to` backends for a given `location` you can also use the `copy` option. Instead of recalculating the backup multiple times, you can copy the freshly copied snapshot from one backend to the other, avoiding recomputation.

+  my-location:
