[CFG] - Commands failing in old versions of DDEV

[davidjguru]

Describe the bug
When you're using versions of DDEV under 1.18 you're facing problems in some installation steps due to non-recognition of special characters, for instance when execute:

- exec-host: "([ $(ddev drush eval 'print_r(array_keys(\\Drupal::entityTypeManager()->getDefinitions()));'

Present in hook pre-start described in config.yml file for DDEV setup. This leads to installation errors and various command execution problems. As the command is not executed correctly, it does not delete the shortcuts and therefore also crashes when importing the configuration.

To Reproduce
Steps to reproduce the behavior:

1. Use DDEV under 1.19 version.
2. Run ddev start after git clone ..., etc.
3. See errors from prompt.

Expected behavior
Download, configure and install all the setup for Summer House as in 1.19 or above versions of DDEV.
