fix(release): avoid jq ARG_MAX limit when encoding CRD files

[Kevin Rudde (kevinrudde)]

Problem

The release workflow's make pr on helm-charts step failed with:

/usr/bin/jq: Argument list too long
##[error]Process completed with exit code 126.

The per-file addition builder passed the whole base64-encoded file as a jq command-line --arg:

jq -n --arg path "$f" --arg contents "$(base64 -w0 "$f")" '{path:$path, contents:$contents}'

Large CRD manifests produce base64 strings that exceed ARG_MAX, so exec fails before jq runs.

Fix

Pipe the base64 contents into jq via stdin (-Rs) instead of passing it on argv — no argument-length limit:

base64 -w0 "$f" | jq -Rs --arg path "$f" '{path:$path, contents:.}'
