Ubuntu 24 CI: Remove libopenblas-base package and update Kokkos build…

… OS (#1041)

### Before submitting

Please complete the following checklist when submitting a PR:

- [ ] All new features must include a unit test.
If you've fixed a bug or added code that should be tested, add a test to
the
      [`tests`](../tests) directory!

- [ ] All new functions and code must be clearly commented and
documented.
If you do make documentation changes, make sure that the docs build and
      render correctly by running `make docs`.

- [ ] Ensure that the test suite passes, by running `make test`.

- [x] Add a new entry to the `.github/CHANGELOG.md` file, summarizing
the
      change, and including a link back to the PR.

- [ ] Ensure that code is properly formatted by running `make format`. 

When all the above are checked, delete everything above the dashed
line and fill in the pull request template.

**Context:**
Github Ubuntu CI has upgraded from 22 to 24, and libopenblas-base
package is no longer present (leads to
[failure](https://github.com/PennyLaneAI/pennylane-lightning/actions/runs/12815891298/job/35735593161#step:7:60))
and needed.

**Description of the Change:**
Removed libopenblas-base package installation for CI tests.

Since ubuntu24 ship with a new version of gcov, when using GCC11/12, we
will get errors like
[these](https://github.com/PennyLaneAI/pennylane-lightning/actions/runs/12817006998/job/35739252160#step:5:191):
```
runner_measurements.cpp.gcno:version 'B14*', prefer 'B33*'
geninfo: ERROR: Incompatible GCC/GCOV version found while processing /home/runner/work/pennylane-lightning/pennylane-lightning/Build/pennylane_lightning/core/src/measurements/tests/CMakeFiles/measurements_test_runner.dir/runner_measurements.cpp.gcda:
	Your test was built with 'B14*'.
	You are trying to capture with gcov tool '/usr/bin/gcov' which is version 'B33*'.
	(use "geninfo --ignore-errors version ..." to bypass this error)
```
With GCC13, lcov will fail with:
```
geninfo: ERROR: mismatched end line for _Z43C_A_T_C_H_T_E_M_P_L_A_T_E_T_E_S_T_F_U_N_C_0IdEvv at /pennylane-lightning/pennylane_lightning/core/src/utils/tests/Test_Util.cpp:32: 32 -> 49
        (use "geninfo --ignore-errors mismatch ..." to bypass this error)
```
I have checked that the [coverage
%](https://github.com/PennyLaneAI/pennylane-lightning/actions/runs/12818512732/job/35744183008#step:5:654)
is still correct with adding `--ignore-errors mismatch`

**Benefits:**

**Possible Drawbacks:**
