Issue #3159842 by smustgrave, andypost, longwave: Fix wording in...

    <env name="SIMPLETEST_DB" value=""/>

    <!-- Example BROWSERTEST_OUTPUT_DIRECTORY value: /path/to/webroot/sites/simpletest/browser_output -->

    <env name="BROWSERTEST_OUTPUT_DIRECTORY" value=""/>

    <!-- To have browsertest output use an alternative base URL. For example if

     SIMPLETEST_BASE_URL is an internal DDEV URL, you can set this to the

     external DDev URL so you can follow the links directly.

    -->

    <!-- By default, browser tests will output links that use the base URL set

     in SIMPLETEST_BASE_URL. However, if your SIMPLETEST_BASE_URL is an internal

     path (such as may be the case in a virtual or Docker-based environment),

     you can set the base URL used in the browser test output links to something

     reachable from your host machine here. This will allow you to follow them

     directly and view the output. -->
