Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):

Increase the limit for opened files in clickhouse-local. It will be able to read from web tables on servers with a huge number of CPU cores. Do not back off reading from the URL table engine in case of too many opened files. This closes #46852.
