[CI][Benchmarks] Fix pushing results to new branch

[PatKamin]

There is a bug that results in Nightly Benchmarks to fail pushing new results to the new results branch on intel/llvm:

[sycl d0defc846] [GHA] Upload compute-benchmarks results from https://github.com/intel/llvm/actions/runs/19053464326

This patch fixes the benchmarking workflow to properly push to the correct sycl-benchmark-ci-results branch.

@sarnex, can you please take a look a this - we need it after merging #20333

@lukaszstolarczuk Done, can I merge or is the Benchmark CI failure related to this PR?

This patch fixes the benchmarking workflow to properly push to the correct llvm-ci-perf-results branch

This doesn't make sense to me. Why are we still pushing to branch in intel/llvm-ci-perf-results? instead of pushing to sycl-benchmark-ci-results branch of intel/llvm

This patch properly pushes to the branch you mentioned, sycl-benchmark-ci-results. I mistakenly used the wrong name in the PR's description, sorry for confusion.

@intel/llvm-gatekeepers, ready to merge. The CI failure is related to issue mitigated in #20537. The custom run of benchmarks that validates this CI change is here: https://github.com/intel/llvm/actions/runs/19062984825.
