fix(create-package): remove unneeded ts-expect-error directives

[ccharly]

Explanation

It seems those directives are not required anymore. If we keep them as is, invoking yarn create-package ... does fail with the following error:

/path/to/core/node_modules/ts-node/src/index.ts:859
    return new TSError(diagnosticText, diagnosticCodes, diagnostics);
           ^
TSError: ⨯ Unable to compile TypeScript:
scripts/create-package/cli.ts:23:5 - error TS2578: Unused '@ts-expect-error' directive.

23     // @ts-expect-error: The CommandModule<T, U>[] signature does in fact exist,
       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
scripts/create-package/cli.ts:46:5 - error TS2578: Unused '@ts-expect-error' directive.

46     // @ts-expect-error: This does in fact exist, but it is missing from our yargs types.
       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
