fix(fastly): Add application/geo+json mime type to compression list

[alexcottner]

Description

We started seeing a failing health check in telescope, showing that application/geo+json was not being compressed in our CDN. Adding this mime type explicitly so it will be compressed going forward.

curl -I "https://firefox-settings-attachments.cdn.allizom.org/main-workspace/regions/ad99625f-7ec0-4fc4-a44d-07afe8f3ed91.geojson" -H "Accept-Encoding:br"

Awesome thanks. I thought we'd already add this one but I obviously don't see it here in the list. Or was it another one we added?

We also added the WASM compression. But this was working and I'm not sure why it stopped.

Thank you :)

We were confused because we were using 2.10, but then Alex found out that:

• v2.9.1 does contain this change

  terraform-modules/google_fastly_waf/main.tf

  Line 29 in 49dfc61

  "application/geo+json",

• v2.10.0 does not contain this change

  terraform-modules/google_fastly_waf/main.tf

  Lines 28 to 29 in 671c95e

  	"application/json",
  	"application/wasm",
