Add VSCode exporter to exporters.md

Signed-off-by: Guilherme Caulada [email protected]

This PR proposes adding the VSCode exporter to the list of available exporters.

This extension exposes metrics related to files and changes done with VSCode so we can build dashboards that track our development, time spent by project, and in the future by branch.

All the default metrics recommended by Prometheus itself for Node.js are also exposed.

More metrics related to development and git should be added in the future, for example, labels related to git to get time spent by branch, as well as other features.
