tools: ynl: avoid dict errors on older Python versions

Browse Source 
Python 3.9.0 or newer supports combining dicts() with |,
but older versions of Python are still used in the wild
(e.g. on CentOS 8, which goes EoL May 31, 2024).
With Python 3.6.8 we get:

  TypeError: unsupported operand type(s) for |: 'dict' and 'dict'

Use older syntax. Tested with non-legacy families only.
