Installation for other editors - missing cd command?

[HaraldJoerg]

The installation instructions at https://github.com/bscan/PerlNavigator#installation-for-other-editors didn't work for me after the most recent change: I had to add a cd server before running tsc (the command was there in older versions of the instructions)

I am not at all familiar with typescript build processes, so I don't know whether the command has been accidentally deleted or whether my workaround was just pure luck - if that's the correct fix I can prepare a PR
