Add pagination to target revision candidates list

Hi,
I have fixed the above issues that I mentioned during testing. I have turned off the drupal form validation for the checkbox,tableselect that are used to select the different revision version. As this is using ajax to load the dynamic options, the drupal for validator create issues. Looks like a common issue in drupal when using ajax. Couple of suggestions that helped me are from the following links -
Reference 1
Reference 2 →

This is the field that was creating issue - revision tableselect

Also from the previous patch this part was added to show and select the latest revision only for the 1st page of the pagination, but I think it should be shown at the top of every pagination page, that is why I have reverted back the changes to default. Following code is from the previous patch -

+    // Add the latest revision if this is the first page of results.
+    if ($this->database->getPagerManager()->getPager()->getCurrentPage() === 0) {
+      $options = [
+        static::LATEST_REVISION => [
+          'revision_id' => [
+            'data' => $this->t('Latest revision'),
+          ],
+          'state' => [
+            'data' => $this->t('Automatically determines the latest revision at time of transition.'),
+            'colspan' => $entity instanceof RevisionLogInterface ? 4 : 1,
+          ],
         ],
-      ],
-    ] + $options;
+      ] + $options;
+    }

I have tested my new patch locally, but need someone else to review this and then we can move this to testing.
Thanks
