Update custom-tlds.ts

[0xOhm]

Note

Low Risk
Appears to only delete a single custom-tlds.ts file/list, with no other code changes visible; low risk unless downstream code still expects the file at build/runtime.

Overview
Removes custom-tlds.ts (previously a custom TLD list/module). No other changes are present in the provided diff, so any impact is limited to consumers that import or rely on this file.
