Description of your changes

Fixes #713

I have:

• Read and followed Crossplane's [contribution process].
• Run make reviewable test to ensure this PR is ready for review.

How has this code been tested

None, this should have no impact, it is essentially the same module reference.

A successful uptest run of Subnet.network: https://github.com/crossplane-contrib/provider-upjet-azure/actions/runs/9383114181

Note

Need to get crossplane/crossplane-tools#63 and crossplane/upjet#389 merged before merging this one, so that we can remove the temporary replace directives.

@gravufo, please ignore the failed uptest run, caused due to the wrong path. But it seems that there are uncommitted changes. Please run make generate and commit all changes.

Done. I didn't realize I would need to run that command since I was just changing things in place, but it seems like the upgrade of upjet had an impact on the resources.

Let's hope this time is the right one :)

PS: I gave rights to maintainers to edit my branch, so if necessary don't hesitate to edit it!

Thanks

@turkenf I fixed the go fmt error, apparently I had to run go fmt on the hack/main.go.tmpl file so that it applies to all generated resources.
Should be good to merge now!
