Invalid syntax highlighting with or condition `||`

**Describe the bug**
Syntax is invalid formatted with `||` at the begging of the line

**To Reproduce**
Steps to reproduce the behavior:
This workflow casuses invalid hightlighting on the last line:
```yaml
name: "CI / CD"

on: workflow_call

jobs:
prepare:
name: "Prepare"
runs-on: "ubuntu-22.04"
outputs:
perform-tests: "${{ steps.should-perform-tests.outputs.perform-tests }}"
perform-lint: "${{ steps.should-perform-lint.outputs.perform-lint }}"

steps:
- name: "Should perform tests"
id: "should-perform-tests"
run: |
echo "perform-tests=1" >> $GITHUB_OUTPUT

- name: "Should perform lint"
id: "should-perform-lint"
run: |
echo "perform-lint=1" >> $GITHUB_OUTPUT

ci:
name: "CI"
runs-on: "ubuntu-22.04"
needs: ["prepare"]
if: >
needs.prepare.outputs.perform-lint == 1
|| needs.prepare.outputs.perform-tests == 1
```

**Expected behavior**
The last line shouldn't be red and slanted.

**Screenshots**

**Extension Version**
`v0.25.8`

No source files or tests are named. Reproduce the provided workflow in VS Code with the GitHub Actions extension, starting from the syntax-highlighting behavior around the multiline `if` expression; done means the line beginning with `||` is no longer shown red and slanted.
