Align sp_HealthParser 2017+ XE time filter to half-open interval

The pre-2017 XML-shred branch used a half-open time filter:

    WHERE ca.utc_timestamp >= @start_date
    AND   ca.utc_timestamp <  @end_date

The 2017+ branch used BETWEEN, which is a closed interval — an event
captured at exactly @end_date was included on 2017+ and excluded on
pre-2017. Same inputs, same data, different results depending on
which branch ran.

Rewrote the 2017+ @time_filter to use explicit `>= AND <` so the
boundary semantics match across versions. Half-open is the more
common convention for time windows in this sproc and avoids
double-counting when callers chain windows end-to-end.

Verified sp_HealthParser installs clean and @what_to_check = 'waits'
runs without errors on SQL Server 2022 (a 2017+ build).
