Combine the video capture and audio recording steps into one 'bash -c' command so users can copy and run it directly, and align the Chinese and English versions.

What this PR does
Follow-up to #2130 (merged): the HDMI audio capture test on the HK628 page is now a single-line command that can be copied and run directly.
bash -c 'v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=NV12 --stream-mmap=3 --stream-poll --stream-count=480 --stream-to=/dev/null >/dev/null 2>&1 & video_pid=$!; sleep 1; arecord -D hw:CARD=sai2capture,DEV=0 -f S16_LE -r 48000 -c 2 -d 5 -t wav rk628-audio.wav; wait "$video_pid"'Previously the same steps were written as a multi-line shell snippet with
\continuations and a blank-line separatedVIDEO_PID=$!/wait "$VIDEO_PID". Copy-pasting it was error-prone; the single-line form keeps the same behaviour (video pipeline stays alive whilearecordrecords) but is safe to paste in one go.The change is made in the shared template
docs/common/accessories/_hdmi-in-to-mipi-csi2-usage.mdx, and the board name / video node / sound card are still template parameters, so other boards inherit it automatically.Scope
Docs only — Chinese (
docs/) and English (i18n/en/) updated together. Requested during review of the adapter usage tutorial.
