Confusing default values for SMTP (TLS/SSL)

[UncleSamSwiss]

Describe the issue

The default values for SMTP are confusing:

https://github.com/WeblateOrg/helm/blob/c009d08912a252305ec0d3bb48ff6c9a468eb91c/charts/weblate/values.yaml#L33-L36

You can always only set one of these to true, otherwise celery complains:

EMAIL_USE_TLS/EMAIL_USE_SSL are mutually exclusive, so only set one of those settings to True.

I already tried

• [X] I've read and searched the documentation.
• [X] I've searched for similar issues in this repository.

Steps to reproduce the behavior

1. Create a helm release without setting either emailTLS or emailSSL to false
2. You won't be able to send emails with the exception below.

Expected behavior

Since port 587 is used in the default values, I would suggest setting only emailTLS to true.
