Service Worker cache stuck on older version

[SgtPooki]

Describe the bug
The context for this bug is from a FIL slack convo between @aschmahmann and @lidel.

Q: When I load the website I get one version and if I do ctrl+f5 (hard reset) in chrome I get another one. If I try loading the website again I'm back to the old version 😭

A: I think it is old cache in service worker – you should be able to purge old version by removing it (below is Firefox, but chromium have similar UI)

Q: cool, that did it thanks 🙏. Is this a bug with an older version of explore.ipld.io or just a thing with service workers? Wouldn't want other people stuck on ancient versions here either

A: I think by default workers expire within 24h, usure why yours was stuck. guess: i think the old version is kept alive as long you have a tab open or something, so if you used it often it was kept around

Q: idk, the version I had was using secio (I could see the wss requests in the browser) and obviously making no progress which is ancient. Pretty sure I've turned off my computer, updated chrome, and probably (although I guess not for sure) closed all my windows during that time.
