Vulcanized Template Route test failure

System information

• Have I written custom code (as opposed to using stock example code provided): No
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Ubuntu 24.04
• Fairness Indicators version: 0.47.0
• TensorFlow version: 2.16.2
• Python version: 3.9, 3.10

Describe the current behavior

The testVulcanizedTemplateRoute test fails because the vulcanized_tfma.js is not found:

self = <tensorboard_plugin_fairness_indicators.plugin.FairnessIndicatorsPlugin object at 0x7b58a01f0a00>, request = <Request 'http://localhost/data/plugin/fairness_indicators/vulcanized_tfma.js' [GET]>

    @wrappers.Request.application
    def _serve_vulcanized_js(self, request):
>     with open(_TEMPLATE_LOCATION) as infile:
E     FileNotFoundError: [Errno 2] No such file or directory: '/home/redacted/path/tensorboard_plugin/tensorflow_model_analysis/static/vulcanized_tfma.js'

Describe the expected behavior

The test should run and pass.

Standalone code to reproduce the issue

Once #387 is merged, the test failure can be reproduced with

$ cd path/to/project/tensorboard_plugin
$ pytest --runxfail tensorboard_plugin_fairness_indicators/plugin_test.py

Start with tensorboard_plugin_fairness_indicators/plugin_test.py:testVulcanizedTemplateRoute and run the provided pytest --runxfail command. Then inspect tensorboard_plugin_fairness_indicators/plugin.py:_serve_vulcanized_js and the referenced tensorflow_model_analysis/static/vulcanized_tfma.js location. Done means the route serves the file, the test passes, and its xfail marker can be removed.
