Link to line numbers in `files` and `dependencies`

[jaimergp]

I would like something like what we have in Github to link to specific line numbers in a file, but pointing to the Files section or the Dependencies section. This is useful to generate shareable links so folks can say things like "hey, this file shoudn't be here!". I've tried to implement it quickly with st.dataframe and also st.columns, but the result was not UX or UI satisfactory. Very clunky.

Ideally this is integrated directly in the st.code component so I'll open an issue.
