Remove node access patch as 10.2 no longer supported

[andybroomfield]

Fix #263
Fix #292

What does this change?

Remove the patch "node_access filters out accessible nodes when node is left joined (1349080)"
This patch will still be required for Drupal installs <10.3, but they should no longer be used.

How to test

As per the original issue, #231 and #147.
Install a module that uses a node_access hook. Eg. View unpublished.

Try to create a service page and service landing page, users should still be able to reference a serivce landing page in the parent if they have persmission to view it.
(Will require using the editor role).

How can we measure success?

Cleaner deploys, service page structure remains intact.

Have we considered potential risks?

Councils may be staying on 10.2 which is now unsupported, they will need to reapply the patch.

#265

Though we might as well go with this one, as it's applying.
In either case it's clear from previous PR, and the issues, that it's been tested and accepted.
