migrations-post-upgrade.yaml fails when using affinity

Chart version: 2.33.0

Since the addition of affinity to the migration templates (see https://github.com/Kong/charts/pull/946/files) The template generation fails with:

From looking at the change it seems that the template mistakenly uses indent instead of nindent; I came to this assumption as all other template commands in the migration templates use nindent while the new affinity is the only one that does not.
