fix Fontkit typing

[jankuca]

The avocode/fontkit library is in plain JS and does not provide types.

This should fix the "Cannot find type definition file for 'avocode-fontkit'" error popping up in TS project builds when a project uses opendesign/sdk.

(WIP, needs to be tested)

This doesn't build out of the box. Is this an issue with the code or the TypeScript config?

$ tsc --outDir dist --sourceMap --declaration --project ./tsconfig-build.json
src/local/system-font-manager.ts:290:39 - error TS7006: Parameter 'fontInfo' implicitly has an 'any' type.

290         fontCollection.fonts.forEach((fontInfo) => {
                                          ~~~~~~~~

It is an issue with missing typing info, not TS config. I did not have time to test this PR yesterday so I just drafted it out.

The any has to be explicit here fontInfo: any for the error to disappear. Since the library does not have types, I think it is OK to do it this way for now.

As a workaround, you can set "skipLibCheck": true in your tsconfig.json

@xorb good workaround, but I'd love to fix this for real. Ping @petrbrzek @rychlis
