fix(codewhisperer): patch #5621 and remove language not yet supported (#5630)

## Problem
disable inlineCompletion support for language `Dart`, `SystemVerilog`,
`Lua`, `Swift`, `Vue`, `Powershell`, `R` which were added by #5621 and
we disable it because service is not ready yet thus will causing 4xx
error `improper formed request`.


## Solution
Disable Dart, SystemVerilog, Lua, Swift, Vue, Powershell, R
