Add 'access geo browser' permissions for editors

[willguv]

Reported by @benhillsjones when adding a directory venue to a new Dumfries and Galloway website

He saw the following:

To replicate, on a new install try adding a directory venue page with a geo location

The expected behavior is to be able to add a geo location

This was fixed locally by Rohallion by adding the 'access geo browser' permission to the Editor role

The permission needs to be added for Editor, Author and Contributor roles, as all may be required to add geo items

This was added 021c3af
Though only fairly recently so if I site was installed before November 2023 it won't have it or any geo permissions unless explicitlly set up.

An update hook to assign this could be possible, but we would need to go through every role checking if the 'access geo_entity_library entity browser pages' had been assigned and, if not, add it to the author and editor roles.

We've just made the same change locally in Essex and it resolved the issue. Would be good to address soon as I imagine every council is having to diagnose and fix this issue - it's wasted effort

PR #121 ready for review:

• Adding the 'create geo' and 'access geo_entity_library entity browser pages' permissions to the default set for the Contributor role too, in .localgov_geo.module.
• Update hook in localgov_geo.install: Grant 'create geo' and 'access geo_entity_library entity browser pages' permissions to Editor, Author and Contributor roles.
