Update hosting_providers.json - add Misk.com

[nitinag]

Free & automated SSL

[bmw]

do you have any documentation about the TLS support misk.com provides its users? see https://github.com/certbot/website?tab=readme-ov-file#hosting-providers-list and in particular this text about what we're looking for here:

• for category, see descriptions here.
• for full/partial categories, one of the links provided should have evidence of being in that category.
• only one of tutorial, announcement, plan will show up, in that order.
  • partial should have tutorial.
  • full providers shouldn't need a tutorial to turn on https. an exception might include instructions of what to do if something goes wrong and the automatic https doesn't work.

Added a link in the announcement parameter that points to the docs from that page:

HTTPS
Every website hosted with us is automatically secured with free ssl certificates that are issued and renewed automatically. There's nothing to enable or manage. Your site is accessible via https.
