Certain linters and formatters support fixing linting and formatting
issues (fix mode). Before this change, Super-linter runs linters and
formatters in a mode that doesn't modify the source code in any way
(check only mode).
With this change, Super-linter supports running linters and formatters
in fix mode if explicitly requested by the configuration. If the
configuration includes a variable named FIX_<language_name>,
Super-linters modifies the command to run the linter or formatter for
<language_name> to enable fix mode.
The modifications to the linter or formatter command that Super-linter
applies depend on what is the default for a particular linter: it either
removes or adds options to the command to run the linter or formatter.
Move LANGUAGE_ARRAY definition and initialization to a dedicated file
(globals/languages.sh) so we can source it in different places without
having to source the whole linter.sh
Move the logic to build the linter versions file outside the main
runtime. There's no need to include it there because it's used only when
building the image.
Move the list of linters by name in linterVersions.sh because we don't
need it in any other place.
