TypeScript and CSS language server templates are not correct and result in failed startup

[SCWells72]

These user-defined language server templates aren't correct. Let me explain for each in turn...

The TypeScript language server does not start properly when created from the template:

Start server command=$USER_HOME$/.lsp4ij/lsp/typescript-language-server/node_modules/.bin/typescript-language-server.cmd --stdio
com.redhat.devtools.lsp4ij.server.CannotStartProcessException: com.intellij.execution.process.ProcessNotCreatedException: Cannot run program "C:\Users\Scott\.lsp4ij\lsp\typescript-language-server\node_modules\.bin\typescript-language-server.cmd": CreateProcess error=2, The system cannot find the file specified
	at com.redhat.devtools.lsp4ij.server.OSProcessStreamConnectionProvider.start(OSProcessStreamConnectionProvider.java:130)
	at com.redhat.devtools.lsp4ij.LanguageServerWrapper.lambda$start$4(LanguageServerWrapper.java:345)

	at java.base/java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java)
	at --- Async.Stack.Trace --- (captured by IntelliJ IDEA debugger)

	at java.base/java.util.concurrent.CompletableFuture.asyncSupplyStage(CompletableFuture.java:1782)
	at java.base/java.util.concurrent.CompletableFuture.supplyAsync(CompletableFuture.java:1989)

In my experience, the correct command to start that language server on Windows is:

npx.cmd typescript-language-server --stdio

and on Mac/Linux it's:

npx typescript-language-server --stdio

Similar with CSS as the template requires VS Code to be installed, but that's not guaranteed to be the case. If instead it just used NPM to install vscode-langservers-extracted, the correct command-line without any other external dependencies would then be:

node C:\Users\Scott\node_modules\vscode-langservers-extracted\lib\css-language-server\node\cssServerMain.js --stdio

Please let me know if that doesn't make sense.

For typescript I did a fix. Please try it.

For css can we not just install vscode css language server?
