Fix typos and YAML syntax issues (#6628)

* chore: remove trailing colon

Fixes a typo that might confuse users who simply uncomment or copy the
example, leading them to encounter invalid YAML.

* fix: using seaweedfs-s3-secret as default secret for COSI deployment

The default secret name containing the seaweedfs_s3_config secret key
is called "seaweedfs-s3-secret" throughout the configuration. This fix
ensures the COSI driver deployment uses the same consistent name.

* chore!: fix typo

BREAKING CHANGE: Changes name of key in helm-values.
