fix: increase TiKV file descriptor limit to resolve failure in integration tests

[gaganhr94]

Description of the PR

Fixes #2841

TiKV requires atleast ~80000 file descriptors but was only getting the default 65,536, causing it to fail on startup with a FATAL error. This prevented the TiKV cluster from bootstrapping properly.

Currently the ci-integration workflow on this PR would fail because the test update in #2830 is not merged yet. Post merging that fix, we would get the error mentioned in #2841. Merging this PR would resolve that issue as well, and the test pipelines will run without any issues.
