Add Pendo Track Events for Weave GitOps CLI

[opudrovs]

Part of #2452

• Added tracking command events with Pendo.

• Added a test for the getCommandPath function.

• Refactored imports where both cmd/gitops/import and pkg/config are imported for consistency.

Notes:

• I've rebased on @joshri 's branch auto-analytics ( https://github.com/weaveworks/weave-gitops/pull/2868 ), so I'll need to wait until it is merged and rebase on main before merging the current PR.

• You can view tracked events in Product > Track Events in the Pendo dashboard, but there is a delay before the events are displayed there.

I think you need to add the new ldflag(s) to .goreleaser.yml too, or only non-release binaries will have the tier set.

Added! 😅
