test: add missing closing brace in TypeScript test files

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• fixes a syntax error present in 126 lines across 42 docs/types/test.ts files, where a $ExpectError test assertion opened an options object literal with { but omitted the closing } before the call's ), e.g. factory( { 'state': true ); instead of factory( { 'state': true } );. The missing brace is a syntax error that prevents the affected test files from compiling. The closing } is inserted so the lines parse and still trigger the expected type error.
• additionally corrects two pre-existing incorrect $ExpectType annotations in random/base/frechet and random/base/triangular. These were masked by the syntax error; once the files compile, the expect-type linter flags them. Both distributions take three parameters, so factory() returns a TernaryFunction (not BinaryFunction), matching the declaration files.

Affected namespaces: random/base, random/array, random/iter, and utils/define-memoized-property.
