feat: :package: SW Caching for Starmaps Requests

[whizzzkid]

Closes #254

In this PR:

• Implemented a custom caching strategy as a workbox plugin.
• Workbox strategies don't allow for caching POST requests by default.
• We can now use response from the cache first and revalidate in the background, this allows for a good compromise between network first and cache first.

Demo:

• Bacalhau Roadmap: https://starmaps-git-feat-sw-ipfs-ignite.vercel.app/roadmap/github.com/filecoin-project/bacalhau/issues/1151
• IPFS Roadmap: https://starmaps-git-feat-sw-ipfs-ignite.vercel.app/roadmap/github.com/ipfs/roadmap/issues/102#detail

⚠️ Risk:

• There can be a scenario where the caches get sticky and don't update.
• We would need to manually validate this before deploying.

Behaviour

• The first load takes time, second load is faster.

Screenshots and Testing

• Service workers strategy using workbox are really hard to test.

  

• To test locally, you can see the responses being cached in the milestones cache:

  

• The revalidation can be seen in the network tab
