fix: inject berlin_group_v1_3_alias_path for local test runs

[hongwei1]

Summary

code.util.ApiVersionUtilsTest asserts ApiVersionUtils.versions.length shouldBe(21).
On a clean local checkout of develop this fails with "20 was not equal to 21",
while CI passes. Root cause: test.default.props is gitignored and each
developer maintains their own local copy, so it silently drifts from what
CI's "Setup props" step injects (.github/workflows/build_pull_request.yml:291,
build_container.yml:297).

Without berlin_group_v1_3_alias_path set, OBP_BERLIN_GROUP_1_3_Alias
reports an empty ScannedApiVersion("","",""), and
ScannedApis.isAddressable filters it out of versionMapScannedApis
entirely — so the local classpath scan finds 5 addressable scanned API
versions instead of 6, and ApiVersionUtils.versions (15 hardcoded +
scanned, deduplicated) comes out to 20 instead of 21.

Fix

Inject OBP_BERLIN_GROUP_V1_3_ALIAS_PATH="0.6/v1" as an env var override in
run_tests_parallel.sh's run_shard function, mirroring the exact pattern
already used for three other known local-vs-CI props gaps in the same
function (OBP_MAIL_TEST_MODE, OBP_DYNAMIC_CODE_SANDBOX_PERMISSIONS,
OBP_ALLOW_USER_GENERATED_SCALA_CODE) — APIUtil.getPropsValue gives
OBP_* env vars priority over the props file, so this closes the gap
without touching the developer's local, gitignored props file.

Testing

Reproduced the failure on a clean origin/develop checkout (commit
a98ba9847d843c6717f7f7aaa6c5cf6488819c9a) with the env var unset — fails
with "20 was not equal to 21". Set only OBP_BERLIN_GROUP_V1_3_ALIAS_PATH
(props file otherwise untouched) and re-ran the same single-suite
invocation run_shard uses (mvn scalatest:test -pl obp-api -DwildcardSuites=code.util.ApiVersionUtilsTest with the same env vars) —
passes.

Note

Found while verifying full-suite results for an unrelated PR
(#2904, deleting retired Lift-era API standards). Confirmed via a
separate clean-checkout reproduction that this failure is unconnected to
that PR's changes — filing as its own fix here rather than folding it in.

Folded into #2904 (commit 103d4e2) at the reviewer's request, rather than keeping this as a separate PR. Closing.
