Revert "Issue-358 | Replace --enable.COLLECTOR with --collector.COLLECTOR (#365)"

This reverts commit 537c995.
Reverted enable.COLLECTOR because it is a breaking change that needs
exahustive testing. By reverting it, we can make the release v0.20.9
without affecting the current behavior for PMM.

 The build process uses the dockerized version of goreleaser so you don't need to install Go.
 Just run `make release` and the new binaries will be generated under the build directory.
