[PATCH v1 4/4] Azurepipeline: SpellCheck: Enforce Node dependency to use version 14.x

["Kun Qin" <kuqin12@gmail.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3445

Per update from Cspell tool, the minimal requirement of Cspell 5.x
regarding Node is 12 and above. This has caused multple Cspell failures
during CI build validation:
"Failed to process "**.c" TypeError: text.matchAll(...) is not a function
or its return value is not iterable"

This change updates the lowest required node version to 14.x to support
Cspell functionalities.
