fix: Allow users to optionally override templates

[wasurerarenai]

Looks like the logic was reversed in #1319. That change allowed non-existant files in bootstrap/templates to be created, but couldn't override existing files. The inputs need to be swapped to allow the overrides to be applied with preference (if they exist).

This affect can be seen in makejinja's examples:

• https://github.com/mirkolenz/makejinja/blob/main/tests/data/makejinja.toml
  • inputs = ["./input1", "./input2"]
• https://github.com/mirkolenz/makejinja/blob/main/tests/data/input1/not-empty.yaml.jinja
• https://github.com/mirkolenz/makejinja/blob/main/tests/data/input2/not-empty.yaml.jinja
• https://github.com/mirkolenz/makejinja/blob/main/tests/data/output/not-empty.yaml

This allowed me to apply a patch to the ingress-nginx instances without changing the source template files.

That makes sense, thanks for providing an update!
