cannot run with read only root filesystem because /home/node/.cache directory cannot be created

When using read only root filesystem in the securityContext:

Error: ENOENT: no such file or directory, mkdir '/home/node/.cache'
2024-01-16T17:47:37.516Z | error    | Error: Exiting due to an error. "{ file: 'LoggerProxy.js', function: 'exports.error' }"
2024-01-16T17:47:37.517Z | error    | Error: ENOENT: no such file or directory, mkdir '/home/node/.cache' "{ file: 'LoggerProxy.js', function: 'exports.error' }"

And there is no extraVolumes/extraVolumeMounts in the values to propagate an emptyDir volume to this path to mitigate the issue.

Happy to accept and review PRs

I've reproduced this issue with Docker:
docker run -v .../n8n:/home/node/.n8n --read-only --platform linux/amd64 -it n8nio/n8n:1.22.3

Fails with this error.
docker run -v .../cache:/home/node/.cache -v .../n8n:/home/node/.n8n --read-only --platform linux/amd64 -it n8nio/n8n:1.22.3

Does not.

Interestingly enough the worker pods don't have this issue even though they are running read only.
