Add support for running pre and post commands

[bradyjoslin]

If you need to run additional shell commands before or after wrangler publish, you can specify them as input to preCommands (before publish) or postCommands (after publish). These can include additional wrangler commands (i.e. build, kv:key put) or any other commands available inside the wrangler-action context.

Sample configuration:

jobs:
  deploy:
    steps:
      uses: cloudflare/wrangler-action@1.2.0
      with:
        apiToken: ${{ secrets.CF_API_TOKEN }}
        preCommands: echo "*** pre command ***"
        postCommands: |
          echo "*** post commands ***"
          wrangler kv:key put --binding=MY_KV key2 value2
          echo "******"

Closes #25

Added a new option to skip publishing as mentioned in #25...

Set the optional publish input to false to skip publishing your Worker project and secrets. Useful in conjunction with pre and post commands. For example, if you only wanted to run wrangler build against your project:

jobs:
  deploy:
    steps:
      uses: cloudflare/wrangler-action@1.2.0
      with:
        apiToken: ${{ secrets.CF_API_TOKEN }}
        publish: false
        preCommands: wrangler build
