Only trim leading empty lines, not tabs, when submitting #%% cells to the interactive window

Fix #7303

The webview interactive window used to trim the code to display in the UI

vscode-jupyter/src/datascience-ui/history-react/redux/reducers/creation.ts

Lines 30 to 31 in 8f50e87

	// Then remove text on the front and back. We only do this for the interactive window
	return removeLinesFromFrontAndBack(text);

so we lost this in the transition to the native interactive window. We 'fixed' this by trimming the code that we put into the NotebookCell, which caused #2552 since we removed all leading whitespace, not just leading empty lines

vscode-jupyter/src/client/datascience/interactive-window/nativeInteractiveWindow.ts

Line 627 in 3aa51df

: cellMatcher.stripFirstMarker(code).trim();

Since the cellhashprovider works with a copy of the original, unmodified source code, and not the actual document.getText(), this shouldn't cause (new) issues with debugging cells in the IW.
