The `code-block` directives in MemorySanitizer.rst and ThreadSanitizer.rst were missing a leading period (`. code-block` instead of `.. code-block`). This syntax error caused Sphinx to fail to recognize the directives, resulting in the the subsequent C code being rendered as plain text rather than a syntax-highlighted block.

The currently broken rendering on the official docs can be seen [here](https://clang.llvm.org/docs/MemorySanitizer.html#id7l) and [here](https://clang.llvm.org/docs/ThreadSanitizer.html#interaction-of-inlining-with-disabling-sanitizer-instrumentation).

Fixed the typos to ensure proper HTML rendering.
