Support for using psalm phar archive as language server

[thbley]

I've tried to set psalm.psalmScriptPath to the location of the psalm 4.4.1 phar file. This did not work (psalm started regular check instead of language-server).
Version psalm-vscode-plugin 1.2.2
Vs-code 1.52.1

Using psalm as a composer library worked as expected.

There seems to be a fix in current master branch, so I compiled the extension from current master and loaded this in vs-code.
Language-server starts as expected when setting psalm.psalmScriptPath to the phar file.
But when I make changes to a php file, the issues that psalm finds are not updated.
When I restart the language-server manually, the issues get updated.

Using the psalm phar archive works now using workspace relative paths in the settings.

Tested with:
php 8.0.9
psalm 4.9.1 (phar)
vscode 1.58.2
vscode extension v2.0.5

Thanks!
