v2: Update namespace, dependencies. Add PhoneLink & migration task

[chrispenny]

Updating master (GraphQL 4) with important changes in 1 (GraphQL 3)

I think for a long time development was only being undertaken for the 1 branch, so master (which was effectively 2) has fallen quite far behind.

• Update Github Actions and Recipe Testing
• Update namespace from Link to LinkField.
• Bring over the PhoneLink model.
• Bring over the LinkableMigrationTask.
• Add missing table_name configuration.
• SiteTreeLink should grab Title from its page, if no title is specified.
• Linting

What I didn't bring over

• Client file changes (Mojmir indicated that these were just linting changes, I think bringing these over will make Add multi link support #45 more difficult to rebase).

Testing

• Page has_one Link::class: tested within the page edit form.
• Page has_many LinkItem, which has_one Link: tested within a GridField edit form.

Issues with GridField edit form

Currently the scaffolded field seems to be a dropdown of existing Link models, rather than a LinkField. I'm not sure why that is.

I think this issue exists in the GraphQL 3 version as well, so probably doesn't have to be solved here.

The workaround is to remove the scaffolded field, and explicitly add a LinkField.

Looking good overall 👍 , found a couple of minor issues though.

Did a quick code review and didn't see anything obviously wrong. I'm assuming that all of this code was more or less lifted from the v1 version of the module.

I tested that the core functionality of the module still works. I tested by adding a link to a page and by creating a Link block.

Didn't test the migration ... I don't have much context on how that other module work.

My main concern is what will happen with the data with the new table name?

Thanks for the changes 👍 I have one minor concern with the frontend assets linting but other than that it's looking really good.

Awesome work 👍 I'm happy with the changes.
