✨ *: Replace 'docker build . -t ${IMG}' with '-t ${IMG} .'

Because folks may have 'docker' aliased to 'podman', and Podman
prefers options before positional arguments [1]:

  $ podman build --help | grep CONTEXT-DIRECTORY
     podman build [command options] CONTEXT-DIRECTORY | URL

Generated with:

  $ sed -i 's/ . -t \([^ ]*\)/ -t \1 ./' $(git grep -l 'docker.*build.* \. ')
  $ git checkout HEAD -- docs
  $ git checkout HEAD -- pkg/plugin/v2 testdata/project-v2*

The docs checkout leaves historical docs alone [2,3,4].  The v2
checkouts are because Adrián and Camila consider this minor and not
worth fixing in v2 [5].
