Little cosmetic tweak.

before:
```yaml
# router configuration
router:
resource: ~ # Required
type: ~
http_port: 80
https_port: 443

# set to true to throw an exception when a parameter does not match the requirements
set to false to disable exceptions when a parameter does not match the requirements (and return null instead)
set to null to disable parameter checks against requirements
'true' is the preferred configuration in development mode, while 'false' or 'null' might be preferred in production
strict_requirements: true

# session configuration
session:
```
after:
```yaml
# router configuration
router:
resource: ~ # Required
type: ~
http_port: 80
https_port: 443

# set to true to throw an exception when a parameter does not match the requirements
# set to false to disable exceptions when a parameter does not match the requirements (and return null instead)
# set to null to disable parameter checks against requirements
# 'true' is the preferred configuration in development mode, while 'false' or 'null' might be preferred in production
strict_requirements: true

# session configuration
