Indentation switches from 2 to 4 spaces if a step uses `env:` or `with:`

[xt0rted]

Describe the bug

If a job contains a step which uses env: or with: then the indentation on subsequent lines switches from 2 spaces to 4 spaces. The issue seems to only persist for the rest of the given job and resets in the next one.

To Reproduce

1. Start out with this file

   on: push
   
   jobs:
     test:
       runs-on: ubuntu-latest
   
       steps:
         - name: Step 1
           run: echo "step 1"
   
         #- name: Step 2
   
         - name: Step 3
           uses: actions/checkout@v2
           with:
             foo: bar
   
         #- name: Step 4
   
         - name: Step 5
           uses: echo "step 5"
           env:
             foo: bar
   
         #- name: Step 6
   
         - name: Step 7
           run: echo "step 7"
   

2. Uncomment step 2, go to the end of the line, press enter then tab, start to type run:

3. The resulting text should be aligned with name from the line above it

4. Uncomment step 4, go to the end of the line, press enter then tab, start to type run:

5. The resulting text will not be aligned with name from the line above it, instead it will be indented an extra 2 characters

6. Uncomment step 6, go to the end of the line, press enter then tab, start to type run:

7. The resulting text will not be aligned with name from the line above it, instead it will be indented an extra 2 characters

Expected behavior

The second line of step's 4 and 6 to be aligned with the line above it.

Extension Version

v0.25.8

Additional context

1. The issue goes away if you switch the file's language from github-actions-workflow to yaml

2. Adding the following to my vscode settings file doesn't help:

   "[github-actions-workflow]": {
     "editor.tabSize": 2,
     "editor.insertSpaces": true,
   },
   

3. The issue happens with and without GitHub Copilot running
