Fix remaining broken javadoc link braces in Context module

[thswlsqls]

Description

• Two {@linkplain} tags in the Context module have the closing } before the label instead of after it, so the link ends early and the label renders as literal text with a stray }.
• Context.java line 45: {@link Scope#close()} closing} becomes {@linkplain Scope#close() closing}, matching the correct anchor on line 42 ({@linkplain #makeCurrent set}).
• StrictContextStorage.java line 128: {@linkplain Context#wrap(Executor)} wrapped executor} becomes {@linkplain Context#wrap(Executor) wrapped executor}.
• These are the sibling cases missed by Fix dead references in Context module javadoc #8486 (Fix dead references in Context module javadoc), which fixed the same class of markup elsewhere.
• Related: Fix dead references in Context module javadoc #8486

Testing done

• Docs-only, test-exempt: no test added; ./gradlew :context:check passed (130 tests).
• Javadoc-text-only change: no public signature change, so jApiCmp reports no diff and no docs/apidiffs update is needed.
