Also, replace obsolete city name "Bangalore" with "Delhi",
and improve doc strings.
* lisp/time.el (zoneinfo-style-world-list)
(legacy-style-world-list): Evidently "Bangalore" was chosen for
Asia/Kolkata to avoid confusion about "Calcutta" vs "Kolkata".
However, it has similar confusion with "Bengaluru".
Use "Delhi" instead, as Delhi is larger, its name has not changed
for some time, and proposals to change its name have so far failed.
See: Sharma MS. Vijay Goel wants Delhi renamed as Dilli, but historians
say it will only spell trouble. Times of India. 2019-07-25.
(zoneinfo-style-world-list): Update doc string. “Posix-style” was
ambiguous as TZDB-style strings are specified only by POSIX.1-2024,
so use “TZDB-style” instead. Say “AREA/LOCATION” to be consistent.
If AREA/LOCATION is unsupported, Emacs signals an error on NetBSD
so don’t imply that some other timezone will be used.
(legacy-style-world-list): Remove ("GMT0BST" "London") and ("CET-1CDT"
"Paris"). These are wrong because neither London nor Paris follow
US DST rules.  Instead, use ("GMT0BST,M3.5.0/1,M10.5.0" "London")
and ("CET-1CEST,M3.5.0,M10.5.0/3" "Paris") if they work, and omit
London and Paris entries otherwise.
