fix: remove stray empty tracked .eslintrc.js from Pipelines assets

[chubes4]

Summary

• Removes an empty, dev-only .eslintrc.js tracked under inc/Core/Admin/Pages/Pipelines/assets/react/.
• The production build strips dotfiles, so the file never ships — but homeboy 0.283.1's release packager enforces tracked-file parity and fails with "Release package is missing 1 tracked runtime file(s): ...eslintrc.js". This blocks all releases from environments running the newer packager.
• The file is 0 bytes and has no runtime purpose.

Why now

Releases under the older homeboy (0.245.0) didn't run this parity check, so v0.162.3 shipped fine. The upgraded packager surfaced this pre-existing hygiene issue.

Test plan

• homeboy release data-machine package preflight no longer reports the missing tracked file.
