Request more information on Plugin submission

[dd32]

Currently on plugin submissions we collect:

• Zip file
• ​Basic checks that they understand what they're doing

That's it, and we then infer everything from that, or ask for it via e-mail afterwards.

Unfortunately there are some things we can't reliably infer from that, such as:

• If they want a specific plugin slug Implemented
• If the plugin is a Block Plugin and should be auto-submitted to that upon approval.
• If the plugin is commercial in nature (Ie. should be in our Commercial Supported section)
• If the plugin is a Community plugin (Ie. is accepting of community submissions via a public code repository and will never be commercialised)

The plugin slug is a hard question to ask before submission, as ideally we'd pre-fill it with a slug based on their submission.

So perhaps this needs to be done as a post-ZIP-submission step where they can update some details after they've passed through the pre-checks of the uploader.
