Fix dependencies the bug in Dockerfile

[mhiuuu]

Like in the first video, to create a docker virtual environment you have to run docker build <the folder contains Dockerfile> -t <your env's name> like in my case it is docker build buildenv -t duckos . However, the randomdude/gcc-cross-x86_64-elf has deprecated dependencies.

ERROR: failed to solve: randomdude/gcc-cross-x86_64-elf-lt:latest: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed

In order to fix this, I found a person who fixed it and you could fix this easily just by changing randomdude/gcc-cross-x86_64-elf to maxbalej/gcc-cross-x86_64-elf-lt:lastest

Small note for everyone: The owner of this repository - and also the person who created the tutorial hasn't posted any video since last year also there has been no update since 2021 so it is probably the repo that has been abandoned. However, feel free to keep this working and tell me if there is anything wrong with my changes
