11524: test: use T.TempDir to create temporary test directory r=Frassle a=Juneezee
# Description
A testing cleanup.
This pull request replaces `ioutil.TempDir` with `t.TempDir`. We can use the `T.TempDir` function from the `testing` package to create temporary directory. The directory created by `T.TempDir` is automatically removed when the test and all its subtests complete.
Reference: https://pkg.go.dev/testing#T.TempDir
```go
func TestFoo(t *testing.T) {
// before
tmpDir, err := ioutil.TempDir("", "")
assert.NoError(t, err)
defer os.RemoveAll(tmpDir)
// now
tmpDir := t.TempDir()
}
```

11586: ci: Fix extraneous alpha draft releases r=AaronFriel a=AaronFriel
The [PR workflow to update Pulumi YAML to 1.0.4](https://github.com/pulumi/pulumi/actions/runs/3642973677) shows that it created a draft release, and this has been the case for all contributors' PRs.
This fixes the extra alpha releases created as a result of pull requests. The job "prepare-release" shouldn't run unless the ci/test label is set, indicating an intent to evaluate the full CI pipeline.
