docs: Run `lint` on TS snippets in markdown when running `doc-check`

[maschad]

Is your feature request related to a problem? Please describe.

The doc-check command compiles Typescript snippets in Markdown files but doesn't enforce the linting rules.
Describe the solution you'd like

Modify the doc-check command to also lint the TS snippets according to the tsconfig.json
