fix guessChromeBinaryPath on Ubuntu 24.04

[divinity76]

This is a strange one:

• On Ubuntu 24.04, shell_exec() does not have access to command
• On Ubuntu 24.04, sh have access to command but it appears bugged, sh -c 'command -v bin1 bin2' will ignore bin2
• To access a 'command -v' that actually check more than the first command, we need to use bash, not sh: bash -c 'command -v bin1 bin2 bin3' will look for all of them.

that sure is a headscratcher...

look at this:

$ command -v google-chrome chromium-browser chrome chromium
/usr/bin/chromium-browser
/snap/bin/chromium
$ php -r 'var_dump(shell_exec("command -v google-chrome chromium-browser chrome chromium"));'
NULL
$ php -r 'var_dump(shell_exec("sh -c '\''command -v google-chrome chromium-browser chrome chromium'\''"));'
NULL
$ php -r 'var_dump(shell_exec("sh -c '\''command -v chromium-browser google-chrome chromium-browser chrome chromium'\''"));'
string(26) "/usr/bin/chromium-browser
"
$ php -r 'var_dump(shell_exec("bash -c '\''command -v google-chrome chromium-browser chrome chromium'\''"));'
string(45) "/usr/bin/chromium-browser
/snap/bin/chromium
"

You are assuming that bash will be available, but it may not. 90% of the containers I worked with didn't have bash (which was super annoying, btw).

Well then we can pick between checking a few common paths, or scanning PATH manually (eg #614 ) 🤔

I think it may be best to just specify the path using config or the CHROME_PATH env var.
