## **Description**
InstallType is a recently added flag to help quickly determine whether a
Sentry issue is coming from a natural webstore install, or a developer
environment. We want to be able to filter by this flag in the Sentry UI.

Added the tag, but also simplified some previous logic from when I added
extensionId to make adding extra attributes less tedious in the future.
We can also use this pattern for tags.

Fixes: #27667 

## **Manual testing steps**

1. Open App
2. Use developer options to trigger a sentry error
3. Go into Sentry UI and verify that installType is a tag in addition to
being in the extra properties.
