Check liveness CI - "cancelled after 10min" often actually means price feeder fails to build or something.

It seams that starport / ignite-cli doesn't work well with go workspaces. Probably it requires compilation with go workspaces to make it working. Log of troubleshooting:

1. when starting the app with ignite cli, one of the step is running go mod verify which fails with the following error (you can repeat it by running go mod verify in price-feeder directory)

   go mod verify
   github.com/umee-network/umee/price-feeder : missing ziphash: open hash: no such file or directory
   

2. ziphash error appears in google search and it's related to go module system
3. it seams either go mod has to be fixed or ignite cli has to be compiled with go workspace to solve this issue

Given the findings above, I'm going to leave this PR until there will be more adoption of go workspaces.
