Deprecate old environment variable inputs

[caendesilva]

Abstract

With the improvements made in #45 we no longer need the following inputs, and thus these are deprecated:

Input Name	Description	Default Value
env-site-name	Set the SITE_NAME environment variable	none
env-site-url	Set the SITE_URL environment variable	none
env-torchlight-token	Set the TORCHLIGHT_TOKEN environment variable	none

Removal Timeline

They will be removed in v2.0.

Upgrade Guide

It's very easy to upgrade, just replace the legacy versions with the following:

- name: Old syntax
  uses: hydephp/action@master
  with:
    # Replace this:
    env-site-name: "'HydePHP Action'"
    env-torchlight-token: ${{ secrets.TORCHLIGHT_TOKEN }}

- name: New syntax
  uses: hydephp/action@master
  with:
    # With this:
    env: |
      SITE_NAME='HydePHP Action'
      TORCHLIGHT_TOKEN=${{ secrets.TORCHLIGHT_TOKEN }}

Of course, you only need to specify the values you actually use.

Manually confirmed to be working:

  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: hydephp/action@deprecate-old-environment-variable-inputs
        with:
          env-torchlight-token: ${{ secrets.TORCHLIGHT_TOKEN }}
          env-site-name: "'HydePHP Action'"
          env-site-url: 'test'
          env: |
            CUSTOM: ENV

# Dump of env vars
"SITE_NAME" => "HydePHP Action"
"SITE_URL" => "test"
"CUSTOM" => "ENV"

(The error is not relevant, it's just because I used dd() on the environment variables.)
