Fix link to panic location on GitHub (#35162)

I had a panic, and it reported


``24c2a465bb/src/crates/assistant_tools/src/edit_agent.rs (L686)
(may not be uploaded, line may be incorrect if files modified)``

The `/src` part seems superfluous, and result in a link that don’t work
(unlike
`24c2a465bb/src/crates/assistant_tools/src/edit_agent.rs (L686)`).
I don’t know why it originally worked (of if it even actually originally
worked properly), but there seems to be no reason to keep that `/src`.

Release Notes:

- N/A
