chore: Enable Go jsonv2 experiment and update the trivy dependency (v0.67.2) (#3572)

It requires the encoding/json/jsontext
package which is only available when the goexperiment.jsonv2 build
tag is enabled. This was causing build constraint errors during
tests and builds.

Changes:
- Add GOEXPERIMENT=jsonv2 to Makefile export and all go build/test
  commands that use env (since env creates a fresh environment)
- Add GOEXPERIMENT=jsonv2 to GitHub workflows that use direct go
  commands (workflows using make inherit it from Makefile)

Fix other dependabot alerts.
