DurationParser: don't strip non-Latin unit words before the config lookup - #857

…okup
The default branch of parse() matches a value+unit pair with
TimeValueUnitRegex, then cleans the captured unit text before looking
it up in DurationParserConfig.timesMap:
m.subgroups(1).replaceAll("""[^'\"a-zA-Z]""", "")
The replacement only keeps '"' and ASCII a-zA-Z, so a unit word in any
non-Latin alphabet (Greek, Cyrillic, etc.) is stripped down to an empty
string before the lookup, even though the exact word is listed in
timesMap for that language. timeUnits.get("") then misses and the
whole parse returns None -- durations expressed in those languages
never parse, regardless of how complete their config entry is.
Replaced a-zA-Z with \p{L} (any Unicode letter), which keeps the
original intent -- stripping the stray punctuation this cleanup exists
for, like the trailing ')' in '(11 min)' -- while no longer discarding
letters outside ASCII.
Verified with a standalone build of the exact replaceAll call: the
reported Greek example ('context 4 ώρες', unit text 'ώρες') is wiped
to "" by the old pattern and preserved by the new one, and the
existing ASCII case this cleanup was written for ('min)' -> 'min')
is unaffected.

Preserve combining marks in configured unit names.
DurationParser builds its lookup from configured keys, so मिनट can reach this code. The cleanup keeps \p{L} but removes the Hindi combining vowel mark (\p{M}), changing the captured key before exact lookup. The lookup then returns None, so this configured non-Latin unit still fails to parse. Preserve Unicode marks at this boundary:
