Metadata missing for one Qiskit SDK API file

[Eric-Arellano]

These never had front matter. Axel said it's fine for now, but we should improve it soon.

Please fix these files: docs/api/qiskit-ibm-provider/ibm-provider.md,docs/api/qiskit/transpiler_builtin_plugins.md,docs/api/qiskit-ibm-runtime/ibm-runtime.md

We need to an else clause here:

documentation/scripts/lib/sphinx/addFrontMatter.ts

Lines 19 to 30 in e872441

	if (result.meta.python_api_name) {
	result.markdown = `---
	title: ${getLastPartFromFullIdentifier(result.meta.python_api_name)}
	description: API reference for ${result.meta.python_api_name}
	in_page_toc_min_heading_level: 1
	python_api_type: ${result.meta.python_api_type}
	python_api_name: ${result.meta.python_api_name}
	---
	${markdown}
	`;
	}

TBD how we determine the title and description!

Update: make sure CI enforces it, per #793.

Perhaps we can use the filename as a fallback?
