Fix issue where you cant delete a bootstrap package (#30146)

Fixes [#30059](https://github.com/fleetdm/fleet/issues/30059)

Fixes an issue where you couldn't delete a bootstrap package. The issue
was an unused json struct tag for DryRun on the
`deleteBootstrapPackageRequest` struct.

I also updated the UI to use the current endpoint to delete a bootstrap
package
