fix(compute): pass ip address to static IP entrypoint

[aniruddhaadak80]

Description

Fixes #14611

The static external IP sample entry point passed external_ipv4 and external_access keyword arguments to a function that accepts only ip_address. Both the canonical Compute client-library recipe and its generated snippet therefore raised TypeError before instance creation. This change updates the recipe to pass the address through the supported argument and regenerates the checked-in snippet with SGS.

A dependency-free regression test executes both entry-point call expressions against the declared function signature, covering the source recipe and generated output.

Validation:

• python -m pytest compute/client_library/snippets/tests/test_static_ip_entrypoint.py -q — 1 passed
• Pre-fix entry-point execution — reproduced TypeError: ... unexpected keyword argument 'external_ipv4'
• python -m ruff check compute/client_library/recipes/instances/ip_address/assign_static_external_ip_to_new_vm.py compute/client_library/snippets/instances/ip_address/assign_static_external_ip_to_new_vm.py compute/client_library/snippets/tests/test_static_ip_entrypoint.py — passed
• python -m black --check compute/client_library/snippets/tests/test_static_ip_entrypoint.py — passed
• python -m mypy --implicit-optional --follow-imports=skip --ignore-missing-imports compute/client_library/snippets/instances/ip_address/assign_static_external_ip_to_new_vm.py — no issues found
• python -m compileall -q on the changed Python files — passed
• Live Compute Engine execution was not run because this regression is isolated to the entry-point call signature.

Code Review

This pull request updates the assign_static_external_ip_to_new_vm function call in both the recipe and snippet files to use the ip_address parameter instead of external_ipv4 and external_access. It also introduces a new AST-based test to verify this entrypoint call. Feedback suggests resolving the path of __file__ to an absolute path before accessing its parents in the test file to prevent potential IndexError issues depending on how the test is executed.

[gemini-code-assist]

Using Path(__file__).parents[2] without resolving the path first can raise an IndexError if the test is executed from within the test directory (where __file__ might be a relative path with fewer than 3 parent directories, e.g., test_static_ip_entrypoint.py). Resolving the path to an absolute path first using .resolve() ensures that .parents[2] always resolves correctly.

Suggested change

	ROOT = Path(__file__).parents[2]
	ROOT = Path(__file__).resolve().parents[2]
