JIRA: https://issues.apache.org/jira/browse/IGNITE-29167

Problem

test_examples is parametrized with the absolute path of each example
script. pytest puts that path into the test id, so the test name depends on
the agent's work directory.

On ci2.ignite.apache.org ("Thin client: Python" in the RunAll chain) agents
have two different work roots, so one test has two names and two histories:

tests.test_examples.test_examples(/opt/teamcity/work/425d7af4e9aa99d9/ignite-python-thin-client/tests/__/examples/read_binary_py)
tests.test_examples.test_examples(/data/tcAgent/work/425d7af4e9aa99d9/ignite-python-thin-client/tests/__/examples/read_binary_py)

From 2026-10-03 to 2026-10-18, master ran read_binary.py 106 times:
25 runs under the first name and 81 under the second. The same happens to all
13 example tests. Because of this:

• the history of each example test is split in two;
• a PR run is compared with only part of the master history;
• a passing rerun on an agent with the other work root does not clear the
  failure, because TeamCity sees it as a different test.

Change

Use the script file name as the parameter id (ids=os.path.basename). The
test still runs the script by its full path. The TeamCity name becomes:

tests.test_examples.test_examples(read_binary_py)

TeamCity will see the 13 example tests as new tests once, and their history
starts again from this change.

Testing

• pytest --collect-only -q tests/test_examples.py shows ids like
  test_examples[read_binary.py] instead of the absolute path.
• With TEAMCITY_VERSION set, teamcity-messages reports
  tests.test_examples.test_examples(read_binary_py).
• flake8 tests/test_examples.py passes.
