Make a release

[katopz]

Usually I did this on github build.yml.

name: Mdbook build

on:
  push:
    branches: ['main']

jobs:
  build:
    name: build
    runs-on: ubuntu-latest
    env:
      MDBOOK_VERSION: '0.4.22'
      MDBOOK_LINKCHECK_VERSION: '0.7.4'
      MDBOOK_MERMAID_VERSION: '0.12.2'
    steps:
      - uses: actions/checkout@v3
        with:
          submodules: true
      - name: Install mdbook
        run: |
          mkdir ~/tools
          curl -L https://github.com/rust-lang/mdBook/releases/download/v$MDBOOK_VERSION/mdbook-v$MDBOOK_VERSION-x86_64-unknown-linux-gnu.tar.gz | tar xz -C ~/tools
          curl -L https://github.com/badboy/mdbook-mermaid/releases/download/v$MDBOOK_MERMAID_VERSION/mdbook-mermaid-v$MDBOOK_MERMAID_VERSION-x86_64-unknown-linux-gnu.tar.gz | tar xz -C ~/tools
          curl -L https://github.com/Michael-F-Bryan/mdbook-linkcheck/releases/download/v$MDBOOK_LINKCHECK_VERSION/mdbook-linkcheck.v$MDBOOK_LINKCHECK_VERSION.x86_64-unknown-linux-gnu.zip -O
          unzip mdbook-linkcheck.v$MDBOOK_LINKCHECK_VERSION.x86_64-unknown-linux-gnu.zip -d ~/tools
          chmod +x ~/tools/mdbook-linkcheck
          curl -s https://api.github.com/repos/zjp-CN/mdbook-theme/releases/latest \
                 | grep browser_download_url \
                 | grep mdbook-theme_linux \
                 | cut -d '"' -f 4 \
                 | wget -qi -
          tar -xzf mdbook-theme_linux.tar.gz -C ~/tools
          echo ~/tools >> $GITHUB_PATH

      - name: Install mdbook-svgbob
        run: cargo install mdbook-svgbob --version 0.2.1

      - name: Build
        run: mdbook build
      # share between different jobs
      - uses: actions/upload-artifact@v3
        with:
          name: book
          path: book/

and it took 4 minutes for this Install mdbook-svgbob step.

So it would be nice if we have released version like mdbook-mermaid so it can reduce build time to <1m there.
Nothing urgent btw, just nice to have.

Thanks.
