Code Review

This pull request adds a schematic to migrate the initialState property of ModalOptions to inputValues. The implementation is a good start, and the suggestion to make the module matching more robust by anchoring the regex has been retained. Additionally, this change would benefit from having tests to ensure the migration works as expected and to prevent future regressions. Please consider adding a test case for this migration.

The regular expression for the module path is not anchored. This could lead to incorrect matches if a module path contains @(siemens|simpl)/element-ng(/modal)? as a substring. To ensure an exact match, it's better to anchor the regex with ^ and $.

Suggested change

	module: /@(siemens|simpl)\/element-ng(\/modal)?/,
	module: /^@(siemens|simpl)\/element-ng(\/modal)?$/,
