fix: restore array parsing for req.query repeated keys (#7181)

fix: restore array parsing for `req.query` repeated keys (#7147)

The default `req.query` extended query parser now sets `arrayLimit: 1000` to restore prior array parsing behavior.

qs 6.14.1 began enforcing `arrayLimit` for bracket notation (`a[]=1&a[]=2&...`) and repeated-key notation (`a=1&a=2&...`), where it had previously been silently ignored. Express has never set `arrayLimit` explicitly, so once 4.22.0 picked up qs `~6.14.0`, the default `arrayLimit` of 20 began taking effect — `req.query.a` for arrays larger than 20 items was returned as an object with integer keys (`{ '0': ..., '1': ... }`) instead of an array.

Prior to qs 6.14.1, the effective ceiling for these notations was qs's default `parameterLimit` of 1000 (also not set by Express). This release passes `arrayLimit: 1000` to keep that practical ceiling, restoring the pre-4.22.0 behavior.

Note: this also unifies array-cap behavior across notations. Indexed notation (`a[0]=...`) was historically capped at qs's default `arrayLimit` of 20 even in older qs versions; after this change it also allows up to 1000 items.
