more core ext's on 4.1.0

there's no particular reason, just update for update sake

https://github.com/ManageIQ/more_core_extensions/compare/179bf40..e5b4501
 - Added Ruby 2.7 support [[ManageIQ#79](ManageIQ/more_core_extensions#79)]
 - Added Process#pause, Process#resume, and Process#alive? [[ManageIQ#73](ManageIQ/more_core_extensions#73)]

array added * `#compact_map` - Collect non-nil results from the block
array added `#tabular_sort` - Sorts an Array of Hashes by specific columns

hierarchy added `#descendant_get` - Returns the descendant with a given name

the two breaking changes:
- **BREAKING**: Moved Object#descendant_get to Class#descendant_get [[ManageIQ#75](ManageIQ/more_core_extensions#75)]
- **BREAKING**: Removed deprecated Enumerable#stable_sort_by [[ManageIQ#76](ManageIQ/more_core_extensions#76)]

a minor header output change was made that hasn't been released yet to make tableize more markdown compliant

see ManageIQ/linux_admin#221
