support metadata in ns for require lines

[oakmac]

Found while testing against the Metabase codebase:

   Batch processing can be disabled by setting the environment variable `MB_DISABLE_GROUPER_BATCH_PROCESSING=true`."
   (:require
-   ^{:clj-kondo/ignore [:discouraged-namespace]}
-   [grouper.core :as grouper]
-   [metabase.models.setting :refer [defsetting]]
-   [metabase.util.i18n :refer [deferred-tru]]
-   [potemkin :as p])
+    [grouper.core :as grouper]
+    [metabase.models.setting :refer [defsetting]]
+    [metabase.util.i18n :refer [deferred-tru]]
+    [potemkin :as p])
   (:import
-   (grouper.core Grouper)))
+    (grouper.core Grouper)))

FYI to anyone who is effected by this bug right now:

You can use the discard form #_{:clj-kondo/ignore ...} above a :require line and it will work.

This actually might be a bug / mistake in the metabase codebase? I see in the clj-kondo documentation that the discard form is intended for :clj-kondo/ignore.
