[clang] Correct confusing header in HLSLDocs (PR #100017)

[Greg Roth via cfe-commits]

https://github.com/pow2clk created https://github.com/llvm/llvm-project/pull/100017

Because AvailabilityDiagnostics.rst mistakenly overlined the "Examples" section, it was included in the generated HLSLDocs page. By demoting it to a subheader, it shouldn't show up as a top-level HLSLDocs page.

By demoting it to a subheader, it shouldn't show up as a top-level
HLSLDocs page.

 As a result, availability based on specific shader stage will only be diagnosed in code that is reachable from a shader entry point or library export function. It also means that function bodies might be scanned multiple time. When that happens, care should be taken not to produce duplicated diagnostics.
