fix: Added Microsoft.DevOpsInfrastructure/pools to removal order (#…

…3516)

## Description

After observing [a few
times](https://github.com/Azure/bicep-registry-modules/actions/runs/11297815667/job/31425540661#step:4:887)
that the removal job for the module
`Microsoft.DevOpsInfrastructure/pools` failed, I figured it is time to
add it to the removal order.
The error usually happens when the removal logic tries to remove the RG
before the Pool - presumably because it breaks the resource's
dependencies (e.g., its VNET) and in turn leaves the resource also in a
broken, unremovable state.
