Typescript Template Review

[danibix95]

Hi,

in this PR it is proposed a new base configuration for lc39 Typescript template. The changes include:

• update Node JS version (from v14 to v16)
• swap Jest with Tap as test framework
• split Typescript test configuration from the build one to allow greater flexibility
• allow running tests in "unsafe mode", which means code is only transpiled before tests execution and no type check is performed (see @swc-node/register).
  Note: at build time types are checked
• update service dependencies
• fix linting and add further eslint config for typescript
• updat Github action

Non mi torna l'uso di swc e tsc usato con emitDeclarationOnly. Ho fatto un test e tsc non è più veloce con emitDeclarationOnly perchè la parte lenta non è la transpilazione di TS, quanto il type checking (che non viene skippato).
