chore(gatsby-telemetry): Bump git-up to v7

[LekoArts]

Description

Follow-up to https://github.com/gatsbyjs/gatsby/pull/36358 because of another security vulnerability.

https://github.com/IonicaBizau/git-up/releases/tag/7.0.0 => https://github.com/IonicaBizau/parse-url/releases/tag/8.0.0

I think our unit tests cover everything for our use case and those passed. So should be fine 🤷
