T8484: typos check workflow added

[kumvijaya]

Change Summary

New GitHub Actions reusable workflow that automatically checks for spelling mistakes (typos) in pull requests. Runs on every PR and reports issues with clickable links to the exact locations in the code.

How It Reports Issues

• Automated PR Comments: Posts a formatted table showing each typo with file:line link
• Clickable Links: Direct GitHub blob URLs to the exact line where typo was found
• Auto-Updates: Comment refreshes when new commits are pushed (no duplicates)
• Format:

  ❌ Typos detected in PR (N found)
  | File | Typo | Suggestion |
  | [file.txt:5](link) | typo | correction |
  

Configuration (Optional)

.typos.toml is not required — workflow works out of the box.

Default exclusions (included automatically):

[files]
extend-exclude = [
  "smoketest/**",
  "mibs/**"
]

Add .typos.toml to your repository only if you need additional exclusions or customizations:

[files]
extend-exclude = [
  "smoketest/**",
  "mibs/**",
  "docs/**",
  "vendor/**"
]

Setup

1. (Optional) Add .typos.toml to your repository if you need custom exclusions
2. Workflow runs automatically on pull requests
3. No configuration needed for default behavior (smoketest/ and mibs/ already excluded)

How to Use

Create a workflow file in your repository that calls this reusable workflow:

name: Check Typos

on:
  pull_request_target:
    types: [opened, synchronize]

jobs:
  typos:
    uses: vyos/.github/.github/workflows/check-typos.yml@T8484-typos-check-workflow
