Add API for SSWG Incubated Projects

[0xTim]

Adds 4 new APIs to serve the SSWG incubated packages. These will be at https://swift.org/api/v1/sswg/incubation/{graduated|incubating|sandbox|all}.json and provide the graduated packages, incubating packages, sandbox packages and all the packages.

This PR also:

• Updates the incubation levels for the packages based on the latest review by the SSWG
• Reworks the Incubated Packages page to split them into 3 tables for each incubation level

@finestructure do you to check that the JSON returned is OK and if we should change it. I know for the 'official' collection (https://github.com/swift-server/sswg-collection) we have extra fields that we don't use but we should be able to rework that script to generate the package collection from the data on Swift.org so it's all in one central place if we want to keep that or just rely on the SPI package collections.

@shahmishal do you know how much traffic https://swiftserver.group/collection/sswg.json gets? Looking at GH it's less that one person a day but I don't know if it's cached

Example JSON returned.

@0xTim We'd need flat URL lists per collection as input. Could they be generated and hosted in addition to these annotated lists?

[finestructure]

If that's a problem I can look into extending our process to handle richer input than just a flat list.

[0xTim]

@finestructure no problem, updated JSON response:

That's great, thanks Tim!

@shahmishal do you know how much traffic https://swiftserver.group/collection/sswg.json gets? Looking at GH it's less that one person a day but I don't know if it's cached

I don't have access to this DNS, it's controlled by swift on server group I think.
