fix(ui): add overflow visible to fix dropdown clipping in ConnectionForm accordion

[fufuShih]

Problem

In ConnectionForm, the default overflow behavior of the Accordion.Root component clips child elements that extend beyond the container boundary, causing dropdown menus inside to not be fully visible.

related: #65007

Solution

Added overflow="visible" to the Accordion.Root so that dropdown menus can render outside the container boundary without being clipped.

But maybe #65085 is also the method to solve it.

Files Changed

Added overflow="visible" to Accordion.Root in ConnectionForm

airflow/airflow-core/src/airflow/ui/src/pages/Connections/ConnectionForm.tsx

Lines 205 to 212 in f13b713

	<Accordion.Root
	collapsible
	defaultValue={["standardFields"]}
	mb={4}
	mt={4}
	size="lg"
	variant="enclosed"
	>

After

          <Accordion.Root
            collapsible
            defaultValue={["standardFields"]}
            mb={4}
            mt={4}
            overflow="visible"
            size="lg"
            variant="enclosed"
          >

Changing overflow doesn't fix this issue. Closing in favor of #65085
