Hi @carrodher,
I just bumped the chart and fixed the markdown issue.
About the commit signature, it wasn't signed when opening the PR, but I think I fixed it before you asked. Did I do something wrong ?

[carrodher]

The DCO check is still failing, see https://github.com/bitnami/charts/pull/29856/checks?check_run_id=31396595990 for some tips about how to fix it

@carrodher It seems to be all ok now.

Thanks for contributing! Please, bump a minor version since it adds a new param.

@dgomezleon Is there something else needed for this review ?
It says 1 approving review is required to merge it but I'm not sure if it's all good.

Thanks !
