[DRE-maint] Bug#1150190: ruby-redis: FTBFS in unstable with ruby-redis-client 0.31.0-1: gemspec requires redis-client = 0.30.1

[Ajayi Olatunji O.]

Additional information, following a suggestion to test a relaxed 
requirement from Pirate Praveen.

I took ruby-redis_6.0.0-1.dsc from the archive and added a quilt patch 
that changes line 52 of redis.gemspec from '0.30.1' to '>= 0.30.1' (full 
patch below).

Result: sbuild in an unstable chroot with ruby-redis-client 0.31.0-1 
installed finished with Status: successful and Lintian: pass. The 
dependency resolution check that failed before now passes.

Limit of this result: the build log says "Run tests for ruby3.3: no test 
suite!", so no tests ran. The result shows only that the package builds 
when the requirement is relaxed. It does not show that redis-rb works 
with redis-client 0.31.0, and I did not run upstream's test suite.

The pin is deliberate upstream. The comment above line 52 in 
redis.gemspec says: "Bump deliberately and re-run the full suite." I 
therefore offer the patch as evidence only, not as a recommended change. 
I have also asked upstream about redis-client 0.31.0: 
https://github.com/redis/redis-rb/issues/1398

Patch used for the test:
