Upgrade typescript version on the devworkspace-generator side

[RomanNikitenko]

Is your task related to a problem? Please describe

• devworkspace-generator uses pretty old version of the typescript,
  see https://github.com/devfile/devworkspace-generator/blob/07dcccb0376848b0fb75e250959c698696cd95b5/package.json#L61
• che-code uses the newest one (comes from the upstream - vscode)
• recently I investigated a problem, like:
  TS2345: Argument of type 'import("/checode-compilation/extensions/che-remote/node_modules/some_type_here' is not assignable to parameter of type 'import("/checode-compilation/extensions/che-remote/node_modules/@eclipse-che/che-devworkspace-generator/node_modules/some_type_here.

So:

• one of types comes from the che-code side,
• another one - from the devworkspace-generator side.

I was able to fix the problem by downgrading typescript version on the Che-Code side.

I believe we should upgrade typescript version on the devworkspace-generator side as soon as possible. After that I will test build of the che-code using the newest version of typescript (VS Code uses this one - so we have to use the same).

Describe the solution you'd like

Upgrade typescript version on the devworkspace-generator side - at the moment it uses a version that was released 3 years ago.
