Walkthrough

Removes a runtime MACOS_VERSION vs CMAKE_OSX_DEPLOYMENT_TARGET fatal check from cmake/tools/SetupMacSDK.cmake, updates the fallback WEBKIT_VERSION value in cmake/tools/SetupWebKit.cmake, and applies non-functional formatting changes in several docs (docs/*).

Changes

Cohort / File(s)	Summary
CMake: macOS SDK cmake/tools/SetupMacSDK.cmake	Removed the runtime check that compared MACOS_VERSION against CMAKE_OSX_DEPLOYMENT_TARGET which previously emitted a fatal error when the OS version was older; other min-target logic and SDK-path detection remain.
CMake: WebKit default cmake/tools/SetupWebKit.cmake	Changed the default fallback value for WEBKIT_VERSION from cc5e0bddf7eae1d820cf673158845fe9bd83c094 to 9a2cc42ae1bf693a0fd0ceb9b1d7d965d9cfd3ea.
Documentation formatting docs/bundler/index.mdx, docs/project/benchmarking.mdx, docs/runtime/utils.mdx	Non-functional edits: changed JavaScript example string delimiters from single to double quotes and adjusted table/header/comment formatting and spacing.

Possibly related PRs

• Update WebKit #26549: Modifies the same CMake files (SetupMacSDK.cmake and SetupWebKit.cmake) and documentation; appears to touch the identical runtime-check removal and WebKit default update.
• update WebKit #26324: Updates cmake/tools/SetupWebKit.cmake (changes default WEBKIT_VERSION and adds WEBKIT_TAG logic), closely related to the WebKit-default change.
• Upgrade WebKit #22499: Changes the fallback WEBKIT_VERSION in cmake/tools/SetupWebKit.cmake, directly related to this PR's WebKit version update.

In `@cmake/tools/SetupWebKit.cmake`:
- Around line 4-5: The WEBKIT_VERSION default value is set to a non-existent tag
("autobuild-preview-pr-149-a9ae9224") which will cause downloads to fail; update
the set(WEBKIT_VERSION ...) call to a valid oven-sh/WebKit autobuild tag (or a
stable release tag) by replacing the string literal in the set(WEBKIT_VERSION
...) invocation with an existing tag value, e.g., fetch the repo tags and pick a
current autobuild tag, or change to a known-good tag like
"autobuild-preview-<valid-hash>" so the build can find the assets.
