VS Code + PHP on macOS Big Sur 11.2.1 - issues with default interpreter

[tuck1s]

Issue Type: Bug

1. Start with PHP 7.4.8 in /usr/local/bin. $PATH has this listed first, rather than the macOS default.

which -a php                       
/usr/local/bin/php
/usr/bin/php

2. Install VSCode PHP extension and xdebug extension
3. Install xdebug following the "wizard" advice
4. Amend /usr/local/etc/php/7.4/php.ini file to enable xdebug:

zend_extension = /usr/local/lib/php/pecl/20190902/xdebug.so
xdebug.mode = debug
xdebug.start_with_request = yes

4. Start VS Code. Confirm in Terminal window that the debugger is active.

php -v
PHP 7.4.8 (cli) (built: Jul 30 2020 02:10:12) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Xdebug v3.0.3, Copyright (c) 2002-2021, by Derick Rethans
    with Zend OPcache v7.4.8, Copyright (c), by Zend Technologies

5. Run phpinfo() in a test script. Output shows

phpinfo()
PHP Version => 7.3.24-(to be removed in future macOS)

which of course doesn't have xdebug active, so stepping etc. doesn't work.

6. Workaround: edit launch.json. Edit the "Launch currently open script" section. Add

            "runtimeExecutable": "/usr/local/bin/php",

7. VS Code then runs the correct PHP version.
