An action to just install Liquibase

[alexeyinkin]

I would like an action that just installs Liquibase so that I can run commands in subsequent steps. The current actions are inconvenient for me because:

• I have a mono-repo, and my configuration is under liquibase directory, and locally I run my commands in that directory. When a current action runs, I can't override the working directory, and so my calls on the local machine and a GitHub workflow differ substantially.
• I have all my properties in liquibase.properties file so that locally I can just run liquibase update. However, the current update action requires me to have changelogFile parameter. This is a duplication as I already have it in my liquibase.properties.
• I need to install Google Cloud Spanner plugin. I put it into liquibase/liquibase_lib, and it's found automatically when I run commands in liquibase directory. With current actions, it can't find the plugin because the working directory is different. So I must fiddle with classpath parameter as in #77

This substantial complexity will go away entirely if I could just have

- uses: liquibase-github-actions/install@v4.27.0

- run: |
    cd liquibase
    liquibase update

hi @alexeyinkin, for your use case I would recommend using the liquibase docker container instead of the default actions. The docker container allows you to setup custom workflows. You could do something like this:

jobs:
  liquibase-update:
    runs-on: ubuntu-latest
    container:
      image: liquibase/liquibase:4.27.0

    steps:
    - name: Checkout Code
      uses: actions/checkout@v3

    - name: Run Liquibase Update
      working-directory: ./liquibase
      run: |
        liquibase update
