Quiet xcstringstool output in generate_strings_catalog

The extract/sync sh calls echo enormous commands (up to 400 file paths per extract batch; a
--stringsdata <path> pair per file on sync), burying the output. Pass log: false and emit
concise progress lines instead. No fastlane/release-toolkit action wraps xcstringstool, so sh
is the invocation; log: false is its clean-output option.
