fix: Fix spelling mistakes in JSDoc comments in .d.ts type declaration files

[vermarjun]

Description

Several spelling mistakes were found in JSDoc comments across 4 .d.ts type
declaration files in the packages/concerto-core/types/ directory.

These are not trivial, JSDoc comments in .d.ts files are part of the
developer-facing API documentation and appear directly in IDE tooltips and
autocomplete hints when developers use this library. Typos here affect the
experience of every consumer of the package.

Typos Found

File	Typo	Correction
lib/model/relationship.d.ts	Contructs	Constructs
lib/model/relationship.d.ts	compatability (×2)	compatibility
lib/model/typed.d.ts	Overriden	Overridden
lib/serializer/objectvalidator.d.ts	resouce (×2)	resource
lib/serializer/resourcevalidator.d.ts	resouce (×2)	resource

Important Note

Since these are generated .d.ts files, the same typos likely exist in the
original source files that generated them. If those aren't fixed too, the
typos will return the next time types are regenerated. It would be worth
checking and fixing the source files as part of resolving this issue.

Impact

• No functional or logic changes
• Affects IDE developer experience (tooltips, autocomplete, hover docs)
