fix: do not allow reserved context keys in ServerContext or UserContext

[ardatan]

Do not allow reserved context keys in UserContext and ServerContext if they don't match

For example, you cannot have request as a key in UserContext or ServerContext unless it is Request like below;

// @ts-expect-error Not allowed
createYoga<{
    request: FastifyRequest
}>(/* ... */);

// But allowed
createYoga<{
    req: FastifyRequest
}>(/* ... */);

// Also allowed
createYoga<{
    request: Request // From Fetch API
}>(/* ... */);

Great idea ! You need help to actually finalize it ?

It'd be great @EmrysMyrddin
There are still issues with TS stuff.
