* Test Alpine linux (See Jerrylum/pros-build)

* Update Dockerfile

* Update Dockerfile

* Use pipx

* Update Dockerfile

* Add root/.local/bin to path

* Make build.sh in the root folder

* Change non-dieted files.

* Add libexec to included files

* add possibly missing /

* Update Dockerfile

* Remove extra folder from mkdir

* remove -r flag

* include arm-none-eabi/lib too

* pivot to deleting stuff from the toolchain folder instead of selectively copying stuff. Starting with arm-none-eabi folder

* Delete share folder instead

* try deleting arm-none-eabi/lib

* forgot the folder prefix

* delete /lib/gcc/arm-none-eabi/13.3.1/arm and /lib/gcc/arm-none-eabi/13.3.1/thumb

* delete all but v7-a+fp in thumb

* forgot /arm-none-eabi-toolchain prefix again

* remove files in RUN rm -f /arm-none-eabi-toolchain/lib/gcc/arm-none-eabi/13.3.1/* but not folders

* Update Dockerfile

* Update action.yml to test externally

* Update Dockerfile with stages

* fix copy from stage

* comment out rm command to test stages

* add back package installation

* Update Dockerfile

* refactor to have more stages

* Update Dockerfile

* Update build-image.yml

* Update build-image.yml

* Update build-image.yml

* Remove line that deletes all 13.3.1 subfiles and subfolders

* Diet some more files 

arm-none-eabi-cpp, arm-none-eabi-gdb, arm-none-eabi-gcc-13.3.1,

* Change dieted files to their actual location (misread on my part)

* Update Dockerfile

* diet some more folders

* we cut too much

* Update build.sh

* Update test.yml

* revert back

* revert back

* Update action.yml

* also remove gbd-py from toolchain bin folder

* Update Dockerfile

* re-add pros-cli

* steal additional thumb deleting from jerryio's container

* Update Dockerfile labels

* Update Dockerfile

* Thanks to @Jerrylum

* Remove total build script runtime from build.sh as it's confusing

* Delete packagelist

* Update README.md

* Update action.yml with v4.0.0

* remove pruning steps

* Update build.sh to use shell instead of bash

* remove bash

* Restore bash

* ♻️ Improved run instruction (#14)

* ♻️ Improved run instruction
- Makes it a little more readable by using heredoc
- Pipes tar.xz to tar to prevent writing it to disk
- Uses brace expansion where possible to shorten
- Don't even write some of the unnecessary files to disk

* split toolchain downloading into seperate RUN command for caching efficency and convert all tar --exclude params to their original rm/find forms.

* Fix broken gcc rm command for /bin/arm-none-eabi-gcc-13.3.1

* fix gcc-13.3.1 removal

* delete long_toolchain variable

* 💄 Remove extra whitespace

* remove package installation from get-dependencies since it's already redone in runner stage and the packages aren't used in the get-deps stage

* Delete commented commands for clarity
