Merge #20035

20035: Bump version of UF2 package r=MrKevinWeiss a=MichelRottleuthner

### Contribution description

Bump UF2 package version. The new version, besides many other things, also includes an improvement to search more potential mount paths, which gives better compatibility for different distros.


### Testing procedure

Test if flashing still works for boards that use UF2 (e.g., `feather-nrf52840`, `feather-nrf52840-sense`, `nrf52840-mdk-dongle`):
`BUILD_IN_DOCKER=1 BOARD=feather-nrf52840-sense make -C examples/hello-world all flash term`

With master you should get this error, during flashing: `No drive to deploy.` if you run it on a distro that mounts your device under something like `/run/media/<username>/FTHRSNSBOOT`, or other paths not supported by the old version. To me this happened on Arch.
**Note: you will still get this error if your system doesn't auto mount the device.** But now it will be found when mounted ;)

With this PR try again with the UF2 util:
`rm -rf build/pkg/UF2`
`BUILD_IN_DOCKER=1 BOARD=feather-nrf52840-sense make -C examples/hello-world all flash term`
It should use the new pkg version and flash successfully:
```
