Track consolidated Edit dropdown usage

What does this MR do and why?

In 16.2, we delivered the ability to open workspaces from the consolidated Edit dropdown where users can edit a project or a file using different editors:

This merge request adds Snowplow telemetry to track the usage of these options. We are using the following values to conform with the event schema usage recommendation:

User action	event.action	event.label
Click "Edit Single File" button	click_consolidated_edit	edit_single_file
Click "Edit in Web IDE" button	click_consolidated_edit	edit_web_ide
Click "Edit in GitPod" button	click_consolidated_edit	gitpod
Click "Edit in Pipeline Editor" button	click_consolidated_edit	pipeline_editor
Click in a workspace	click_consolidated_edit	workspace

Reasoning We are grouping all clicks to the Edit dropdown using the click_consolidated_edit action. We use the label field to identify the specific editor preferred by the user.

Screenshots or screen recordings

This merge request doesn't introduce user-facing changes.
