rook: apply patch to use jq for ceph osd dump json output

[ushitora-anqou]

Note that the rook Docker image has jq installed:

❯ docker run -it --entrypoint=sh ghcr.io/cybozu/rook:1.18.6.1 -c "jq --version"
jq-1.6

cf. ushitora-anqou/rook@7733217

Use jq to fix invalid JSON from ceph osd dump

The ceph osd dump -f json command can output invalid JSON containing
values like "inf" which cannot be parsed by encoding/json. This causes
errors like "invalid character 'i' looking for beginning of value".

Fix this by piping the output through jq, which accepts such invalid
JSON and outputs valid JSON that encoding/json can parse.

Pull request overview

This PR updates the custom rook container build to apply an upstream patch that normalizes ceph osd dump -f json output via jq, avoiding failures when Ceph emits non-JSON numeric tokens like inf.

Changes:

• Apply a patch to Rook’s GetOSDDump to pipe JSON through jq before unmarshalling.
• Add an upstream unit test (in the patch) covering both valid JSON and inf-containing output.
• Bump the image tag from 1.18.6.1 to 1.18.6.2.
