[laravel-shift]

This is an automated pull request from Shift to update your package code and dependencies to be compatible with Laravel 9.x.

Before merging, you need to:

• Checkout the l10-compatibility branch
• Review all comments for additional changes
• Thoroughly test your package

If you do find an issue, please report it by commenting on this PR to help improve future automation.

:warning: Shift updated your build matrix for Laravel 10. However, since you are supporting older versions of Laravel, you need to add the following exclusions:

exclude:
  - laravel: 10.*
    php: 8.0

:warning: Shift detected GitHub Actions which run jobs using a version matrix. Shift attempted to update your configuration for Laravel 10. However, you should review these changes to ensure the desired combination of versions are built for your package.

:alembic: Using this package? If you would like to help test these changes or believe them to be compatible, you may update your project to reference this branch.

To do so, temporarily add Shift's fork to the repositories property of your composer.json:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/laravel-shift/translation-sheet.git"
        }
    ]
}

Then update your dependency constraint to reference this branch:

{
    "require": {
        "nikaia/translation-sheet": "dev-l10-compatibility",
    }
}

Finally, run: composer update
