False Positive: Magento2.Legacy.InstallUpgrade.ObsoleteInstallDataScript

### Preconditions

1. Package contains data patch `\VendorName\ModuleName\Setup\Patch\Data\InstallData` (exact nature of data patch irrelevant)

### Steps to reproduce

1. Run the coding standard against the file `Setup/Patch/Data/InstallData.php`

### Expected result

1. Sniff `Magento2.Legacy.InstallUpgrade.ObsoleteInstallDataScript` to not be triggered by the presence of a data patch named `InstallData`, as it is not a `Setup/InstallData.php` script.

### Actual result

1. Data patch fails due to `Magento2.Legacy.InstallUpgrade.ObsoleteInstallDataScript` sniff.

### Misc Notes:

- Possible to disable failure with `phpcs:ignore Magento2.Legacy.InstallUpgrade.ObsoleteInstallDataScript` annotation within the file. Line must be present on line 1, after the opening PHP tag.

Locate the implementation and tests for Magento2.Legacy.InstallUpgrade.ObsoleteInstallDataScript, then reproduce the sniff against Setup/Patch/Data/InstallData.php. Confirm that a data patch with this name is not flagged while the intended Setup/InstallData.php case remains detected.
