json: add kernel_version field to images output

[igorpecovnik]

Summary

• Add kernel_version field to armbian-images.json output
• Extract kernel version from image filename using regex
• Example: 6.6.62 extracted from Armbian_24.11.1_Bananapi_bookworm_current_6.6.62_xfce_desktop.img.xz

This allows users to filter and identify images by their kernel version.

Test plan

• Run the script and verify kernel_version field is populated correctly
• Check JSON output includes kernel_version for all image types

Walkthrough

The PR modifies scripts/generate-armbian-images-json.sh to add a new JSON column kernel_version and populate it for each asset. It extracts KERNEL_VERSION from image filenames (handling Armbian and community variants, stripping suffixes and extensions) and inserts kernel_version between file_extension and platinum in the header. The script updates both main board asset lines and reusable-board outputs to include the computed kernel version while keeping existing fields and output structure intact.

In `@scripts/generate-armbian-images-json.sh`:
- Around line 552-557: The regex used to set KERNEL_VERSION from IMAGE_NAME
shifts fields when the version has a suffix (e.g., -trunk); update the pattern
in the if [[ "$IMAGE_NAME" =~ ... ]] so the version token allows an optional
suffix (consume any non-underscore chars after the numeric version) and make the
kernel capture the correct group (adjust BASH_REMATCH index accordingly);
specifically modify the regex to include an optional non-capturing segment after
the numeric version so the kernel field is always in the same capture group,
then set KERNEL_VERSION from that stable BASH_REMATCH entry (replace the current
pattern and the BASH_REMATCH[2] usage with the new group index).

In `@scripts/generate-armbian-images-json.sh`:
- Around line 552-568: The KERNEL_VERSION extraction is being truncated to the
major version by the parameter expansion KERNEL_VERSION="${KERNEL_VERSION%%.*}";
replace that truncation by first removing any image file extension using the
existing strip_img_ext helper and keep the full semantic version (e.g.,
"6.6.62") — i.e., after selecting the token into KERNEL_VERSION (from IMAGE_NAME
via the f array) call KERNEL_VERSION="$(strip_img_ext "$KERNEL_VERSION")" and
keep the existing variant-stripping KERNEL_VERSION="${KERNEL_VERSION%%-*}" but
remove the erroneous KERNEL_VERSION="${KERNEL_VERSION%%.*}" line so the full
version is preserved.
