chore(deps): disable dependabot from updating pyside6-essentials (#507)

PySide6-Essentials is pinned to 6.8.3 in the gui extra to align with VFX
Reference Platform 2026, so Dependabot bumps for it are never actionable
and just need closing by hand (e.g. #503, which proposed 6.8.3 -> 6.11.1).

Mirrors the ignore rule already present in aws-deadline/deadline-cloud,
but as a bare dependency-name. deadline-cloud uses versions: ["6"], which
pip parses as the exact requirement '= 6' and so only ignores 6.0 -- it
would not have suppressed the 6.11.1 bump. Omitting both versions and
update-types resolves to ALL_VERSIONS (">= 0") in dependabot-core, which
ignores every update for the dependency.

The glob also guards against the manifest's mixed casing
(PySide6-Essentials) and any sibling pyside6-* package.
