HackStudio: Decrease the maximal crash frequency of the server to 10 sec

The maximal crash frequency of the language server was previously 3
seconds, but in practice it was too high.
When working with larger projects the language server can get into a
"crash and respawn" loop that takes more than 3 seconds.

10 seconds seems like a reasonable threshold beyond which we no longer
attempt to respawn the server.
