refactor(ci): Minor yml cleanup (microsoft#22660)

## Description

- Remove a `workingDir` node at the incorrect indentation level. The
script itself checks if that directory exists before `cd`ing into it if
applicable, so having it run in it from the start doesn't seem necessary
(and might even fail if it doesn't exist?)
- Replace a few `tag` strings with the more explicit `Tag image` in
`Docker@1` tasks, as listed [in the
docs](https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/docker-v1?view=azure-pipelines).
`tag` works as an alias, but the explicit version helps so VSCode
doesn't report problems/unexpected values in yml files.
