findDirectivesInScriptCommand trims quotes from custom command files, breaks help text of provided commands

[diegoe]

Describe the bug
In findDirectivesInScriptCommand, spaces, quotes, and double quotes, are trimmed from strings in the command description:

    for scanner.Scan() {
        line := scanner.Text()
        if strings.HasPrefix(line, "## ") && strings.Contains(line, ":") {
            line = strings.Replace(line, "## ", "", 1)
            parts := strings.SplitN(line, ":", 2)
            parts[1] = strings.Trim(parts[1], " \"'")
            directives[parts[0]] = parts[1]
        }
    }

This breaks the formatting of help lines in the default provided commands (example, cmd/ddev/cmd/global_dotddev_assets/commands/web/drush)

$ ddev drush --help
(...)
Examples:
  ddev drush uli" or "ddev drush sql-cli" or "ddev drush --version
(...)

Versus the source:

#ddev-generated
## Description: Run drush CLI inside the web container
## Usage: drush [flags] [args]
## Example: "ddev drush uli" or "ddev drush sql-cli" or "ddev drush --version"
## ProjectTypes: drupal7,drupal8,drupal9,backdrop
(...)

To Reproduce
Run commands like ddev drush --help

Expected behavior
String is passed as is, or at least the provided commands don't fall into this bug.
