Update LfMerge to use Mercurial 6 and .NET 8

rmunn commented 6 months ago

Fixes #1788

Description

LfMerge has been on Mercurial 3 for a long time, and we've had constant trouble with HTTPS certificates because our Mercurial version was too old to support SNI. Moving to Mercurial 6 (and Python 3) will fix that.

Screenshots

Demonstrate any UI / behavioral changes with screenshots or animations.

FWIW the error I receive before this merge (and that this PR should address) looks like this in the lfmerge logs: System.ApplicationException: abort: error: [SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:727)
