[hongbo-miao]

A small fix, however, took me a while to figure out those spaces should not be there 🥲

@sdaberdaku PTAL

@nineinchnick the proposed correction is right.
You can see how the indentation should be in test-values.yaml.
@hongbo-miao sorry for this mistake!

@hongbo-miao can you update the Chart's README to match the changes in values.yaml? See the CI failures.
