icalendar 7.2.1 and 7.2.2 released

[stevepiercy]

The icalendar team is pleased to announce that icalendar 7.2.1 and 7.2.2 have been released.

7.2.1 is a security fix.

Fixed GHSA-qjcq-q7h7-r74v: (GHSA-qjcq-q7h7-r74v) a crafted REPEAT on a VALARM could exhaust memory or CPU via Alarm.triggers and Alarms. Expansion is now capped at icalendar.config.MAX_ALARM_REPEAT. Its default is 10000. Set to -1 to disable the cap. vInt now also enforces the RFC 5545 signed 32-bit integer range on parse.

7.2.2 fixed duplicate vInt.min and vInt.max descriptions in the API reference that caused the documentation build to fail.
