Update coverage test setup, TARPAULIN(TEST + COVERAGE)

[prabakaranklst]

The coverage test (TARPAULIN(TEST + COVERAGE)) fails with stack overflow error for test case test_mt_one_pop_one_stealer.

After analysis, it is found that the failure occurs with Rust toolchain nightly version 1.94.0. It works fine with older versions. So, update the test setup in cargo_required.yml with appropriate tool version and other options for coverage test.
