'Property outputLatency does not exist' - when compiling with TypeScript 4.4+

[Saiyato]

When compiling (doesn't really seem to matter which version of NodeJS/NPM) against the latest version of TypeScript I'm getting the below error:

/ # make -C snapweb/
make: Entering directory '/snapweb'
tsc --build page/tsconfig.json

                                                                                                                   ~~~~~~~~~~~~~

Found 3 errors.

make: *** [Makefile:6: tsc] Error 1
make: Leaving directory '/snapweb'

I can solve this by using TypeScript 4.3 or lower, instead of latest.

Not sure if it's something that can be fixed in code (or references), since I'm not familiar with TS (or C++ for that matter :wink:) In any case, I hope this helps people trying to compile with containers (Docker).
