fix(tui): set id parameter in OSC 8 sequences (#29840)

The id parameter is used to communicate to the terminal that two URLs
are the same. Without an id, the terminal must rely on heuristics to
determine which cells belong together to make a single hyperlink.

See the relevant section in the spec [1] for more details.
