Update go in CI docker image `/jkito/bitmask-vpn:latest`

New issue - came from !186 (comment 1192728)

In the CI, we use registry.0xacab.org/jkito/bitmask-vpn:latest.

I checked the docker image, used for the tests: it has go 1.22 installed.
In go.mod, we have go 1.19

git pull sudo docker pull registry.0xacab.org/jkito/bitmask-vpn:latest
sudo docker pull  registry.0xacab.org/jkito/bitmask-vpn:latest

root@1cf11831572a:/# go version
go version go1.20.3 linux/amd64

Can we update to 1.22.2+ fo fix: https://pkg.go.dev/vuln/GO-2024-2687?
