In github-action release step replace set-output with GITHUB_OUTPUT

[etolbakov]

The following line causes warnings

excalidocker-rs/.github/workflows/release.yml

Line 234 in 4e64a2a

run: echo ::set-output name=VERSION::$(grep "^version" Cargo.toml | awk '{print $3}' | tr -d '"')

The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

As per Github recommendation a workflow using save-state or set-output like the following

- name: Save state
run: echo "::save-state name={name}::{value}"

- name: Set output
run: echo "::set-output name={name}::{value}"

should be updated to write to the new GITHUB_STATE and GITHUB_OUTPUT environment files:

- name: Save state
run: echo "{name}={value}" >> $GITHUB_STATE

- name: Set output
run: echo "{name}={value}" >> $GITHUB_OUTPUT
