Remove pipelines related to a deprecated core_web_vitals dataset

[max-ostapenko]

Related to the deprecation of Looker Studio reports that used core_web_vitals dataset:

• core_web_vitals.technologies table for https://lookerstudio.google.com/u/0/reporting/55bc8fad-44c2-4280-aa0b-5f3f0cd3d2be/
• core_web_vitals.technology_matrix table for https://lookerstudio.google.com/u/2/reporting/0ad64c8f-644a-40f9-93e4-0ccd5f72b33d

we'll remove deprecated pipelines.

No more updates after Dec 2025 release of CrUX.

Pull request overview

This PR removes the technologies.js pipeline from the core_web_vitals dataset as part of deprecating the associated Looker Studio reports. However, the removal appears incomplete as several dependent pipelines still reference the table being deleted.

Key Changes:

• Removes the entire definitions/output/core_web_vitals/technologies.js file (236 lines)

Comments suppressed due to low confidence (1)

definitions/output/core_web_vitals/technologies.js:1

• Deleting this pipeline will break multiple dependent pipelines in the reports schema that reference core_web_vitals.technologies. The following files will fail when this table is removed:

• definitions/output/reports/cwv_tech_adoption.js (line 25)
• definitions/output/reports/cwv_tech_core_web_vitals.js (line 93)
• definitions/output/reports/cwv_tech_lighthouse.js (line 70)
• definitions/output/reports/cwv_tech_page_weight.js (line 60)

These dependent pipelines should either be removed as well, or updated to use an alternative data source before removing this table.

Additionally there is:

• a Looker technologies matrix report - @rviscomi, there were no users during last 30 days - any further plans for it?
• routines saved to the dataset - @tunetheweb, do we still need these?

[rviscomi]

No plans, removing SGTM 👍

[tunetheweb]

Thanks for keeping things clean!

routines saved to the dataset - @tunetheweb, do we still need these?

They used to be a lot more complex, but now they're fairly simple so don't really need to be in a routine. Let's keep em until end of January where we can see if anyone from Web Almanac is needlessly using these still, and then migrate if they are.
