Add file handle limit setting for Alpine (#94439)

* Add file handle limit setting for Alpine

Alpine does not automatically increase the file handle limit to the maximum. #82719 (comment)
As a result we need to increase the limit manually, as we are seeing "Too many files" errors.

* Bump limit to hard cap

* Remove space
