Reformat specs and docs affected by heritage formatter change

Apply the new `is`/`extends` inline formatting (#11009) to committed artifacts
that the formatter now reformats: the http-client-java test spec
arm-customization.tsp and the 1.11 release-notes embedded example. Whitespace
only, no semantic change.
