Malformed shell syntax for CORS_ALLOW_ORIGIN recipe defaults

[fyrye]

The default recipe installs with
CORS_ALLOW_ORIGIN=^https?://(localhost|127\.0\.0\.1)(:[0-9]+)?$

Which errors when loaded from shell.

source ./.env

Result

./.env: line 48: syntax error near unexpected token `('
./.env: line 48: `CORS_ALLOW_ORIGIN=^https?://(localhost|127\.0\.0\.1)(:[0-9]+)?$'

---

To resolve the issue, wrap the pattern in double quotes, which will be parsed out by symfony/dotenv and be properly configured in shell

CORS_ALLOW_ORIGIN="^https?://(localhost|127\.0\.0\.1)(:[0-9]+)?$"
