This patch fixes the indentation in the `encryption` section.
Previously configuration like this:
```yml
cilium_encryption_enabled: true
cilium_encryption_type: wireguard
```
Would template to a `values.yaml` file with indentation that looks like this:
```yml
encryption:
enabled: True
type: wireguard
nodeEncryption: False
```
instead of this:
```yml
encryption:
enabled: true
type: wireguard
nodeEncryption: false
```
This syntax issue causes an error during Cilium installation.
This patch also makes all boolean values in this template file go through the `to_json` filter.
Since values like `True` and `False` are not compliant with the YAML v1.2 spec,
avoiding them is preferable.
`to_json` may be used for all other values in this template to ensure we end up with
a valid YAML document in all cases (even when various strings include special characters),
but this was left for another (future) patch.
