build(deps): Bump basic-ftp to 6.2.6 to resolve DoS advisory (#7024)

Refresh yarn.lock to move basic-ftp onto a patched release:

- basic-ftp: 6.2.2 -> 6.2.6 (uncaught TypeError in the MLSD
  directory-listing parser via __proto__ fact name, DoS in
  Client.list()) [#748]

Transitive dev/CI-tooling dependency (get-uri / proxy-agent via
Appium/WebdriverIO); not shipped in @sentry/react-native. Lockfile-only;
stays within the existing ^6.2.2 range.
