Macro fails to execute in .env file

[MaxOfLondon]

Describe the issue

The .env file fails to parse into container env variable when using marcro.
.env file:

SECRET_USER={{ "kestra" | base64encode }}
SECRET_PASS=base64encoded.password

docker-compose.yml (relevant section)

services:
  kestra:
    image: kestra/kestra:latest
    env_file:
      - .env

The error:
io.kestra.core.secret.SecretService Could not decode secret 'SECRET_USER', make sure it is Base64-encoded: Illegal base64 character 7b
The character 7b is an ascii {, the first character of the macro template.

In comparison, the SECRET_PASS with base64 encoded value correctly maps to a variable.

The debug {{ secret('USER') }} retuns empty string.
