Make pulumi login respect configuration in Pulumi.yaml

[tgummerer]

While working on #1081, we noticed that pulumi login wasn't respecting the configuration in Pulumi.yaml, and thus errored out when no cloud-url was given in the action. We should improve pulumi login, so it takes the setting in Pulumi.yaml into account if that file is available to reduce confusion for users.

I'm facing the same issue.

Workaround:

- id: prepare
  run: |
    cloudUrl=`cat Pulumi.yaml | yq '.backend.url'`
    echo "cloudUrl=$cloudUrl" >> $GITHUB_OUTPUT

OK had a look into this and pulumi login does respect the backend set in the Pulumi.yaml. It looks like the issue is actions isn't running the initial login command in the same directory as all the other commands.
