Pester v6 removed the It -Pending parameter, but two rule tests still used it, causing test run failures unrelated to whatever change is under test.

Changes

• Tests/Rules/UseIdenticalMandatoryParametersForDSC.tests.ps1: -pending → -skip.
• Tests/Rules/UseToExportFieldsInManifest.tests.ps1: -pending:($IsCoreClr) → -skip:($IsCoreCLR), also correcting the casing of the automatic variable.

# before
It "suggests corrections for AliasesToExport with wildcard" -pending:($IsCoreClr) {

# after
It "suggests corrections for AliasesToExport with wildcard" -skip:($IsCoreCLR) {

Behavior is unchanged — both tests remain unexecuted, now via the supported parameter. A Pester discovery-only run reports Skip=True for both, and no other -Pending usages remain in the PowerShell test files.

• Fixes The only test failures are due to -Pending (removed in Pester v6) still used in 2 rule tests unrelated to this PR #2207
