build: enable TypeScript useUnknownInCatchVariables compiler option

clydin · clydin · commit db779eea8472 · 2022-06-13T15:53:11.000-04:00
Enables the TypeScript `useUnknownInCatchVariables` option. This option
provides additional code safety by ensuring that the catch clause variable
is the proper type before attempting to access its properties.
