Adjust code for github.com/olekukonko/tablewriter 1.x API
The API of the `github.com/olekukonko/tablewriter` module was completely redesigned prior to the 1.0.0 release. This made it incompatible with the code written for the API of the 0.0.x versions of the module. These code changes are purely refactoring. There are some changes to the output of the code in the ruledocsgen package, but these are only insignificant changes to the format of the generated markup, which do not result in any changes to the rendered rules documentation content displayed on the website. The previous version of `github.com/olekukonko/tablewriter` had a bug that caused it to incorrectly add a blank line when the cell content contained an explicit line break. That bug has been fixed, and so the code in `internal/result/result.go ` previously required to work around the bug has been removed.
