doc: fix article usage before vowel-sound acronyms

Several prose references to HTTP, HTTPS, SSL, HPE_HEADER_OVERFLOW and ECMAScript used the article "a" where the acronym starts with a vowel sound and should take "an". The rule is based on pronunciation, not spelling: HTTP is read "aitch-tee-tee-pee", SSL is read "ess-es-el", ECMAScript is read "ek-mah-script", and HPE is read "aitch-pee-ee" — all starting with a vowel sound. Affected files: * doc/api/crypto.md — "disable a SSL 3.0/TLS 1.0 vulnerability" * doc/api/http.md — five occurrences ("a HTTP '400 Bad Request'", "a HTTP '431 Request Header Fields Too Large'", "a HTTP/1.1 102 Processing message", two copies of "use a HTTP parser") plus two references to "a HPE_HEADER_OVERFLOW" * doc/api/http2.md — two code-sample comments reading "// Detects if it is a HTTPS request or HTTP/2" * doc/api/module.md — "compiles a CommonJS, a ECMAScript Module, or a TypeScript module" (only the middle article changes; the adjacent "a CommonJS" and "a TypeScript" are both correct) * doc/api/tls.md — two references to "part of a SSL/TLS handshake" in tlsSocket.getFinished() and tlsSocket.getPeerFinished() No behavior changes, documentation only.
