V4: .env variables do not work in serverles.yml

[gsavvidis96]

Issue description

In serverless v3, this serverless.yml file successfully deploys:

service: test
frameworkVersion: "3"
useDotenv: true

provider:
  name: aws
  runtime: nodejs20.x
  region: eu-south-1
  profile: ${env:AWS_PROFILE}
  deploymentMethod: direct
  httpApi:
    cors: true

functions:
  custom:
    handler: handler.handler

While in serverless v4 with the equivalent serverless.yml configuration I get an error:

service: test

provider:
  name: aws
  runtime: nodejs20.x
  region: eu-south-1
  profile: ${env:AWS_PROFILE}
  deploymentMethod: direct
  httpApi:
    cors: true

functions:
  custom:
    handler: handler.handler

As per docs, environment variables from a .env file should load by default.

If I replace ${env:AWS_PROFILE} with a hardcoded profile, it works fine.
