Sync config generation CLI options with Rubocop

[nschonni]

Here is the current --help from Rubocop 1.48.0

Config Generation:
        --auto-gen-config            Generate a configuration file acting as a
                                     TODO list.
        --regenerate-todo            Regenerate the TODO configuration file using
                                     the last configuration. If there is no existing
                                     TODO file, acts like --auto-gen-config.
        --exclude-limit COUNT        Set the limit for how many files to explicitly exclude.
                                     If there are more files than the limit, the cop will
                                     be disabled instead. Default is 15.
        --no-exclude-limit           Do not set the limit for how many files to exclude.
        --[no-]offense-counts        Include offense counts in configuration
                                     file generated by --auto-gen-config.
                                     Default is true.
        --[no-]auto-gen-only-exclude Generate only Exclude parameters and not Max
                                     when running --auto-gen-config, except if the
                                     number of files with offenses is bigger than
                                     exclude-limit. Default is false.
        --[no-]auto-gen-timestamp    Include the date and time when the --auto-gen-config
                                     was run in the file it generates. Default is true.
        --[no-]auto-gen-enforced-style
                                     Add a setting to the TODO configuration file to enforce
                                     the style used, rather than a per-file exclusion
                                     if one style is used in all files for cop with
                                     EnforcedStyle as a configurable option
                                     when the --auto-gen-config was run
                                     in the file it generates. Default is true.

A few of the ones I've seen as helpful

• --regenerate-todo Reads the line from the top of the config to re-run with the same options. Currently this wouldn't really apply except for the current --auto-gen-exclude-limit which isn't currently written to that string today (0.45)
• --[no-]auto-gen-timestamp reduces the git noise when regenerating the file if there is not changes
• --exclude-limit, currently named --auto-gen-exclude-limit in haml-lint. --no-exclude-limit is just an extreme version of this one
• --[no-]offense-counts, similar to the timestamp, it can be useful in reducing source control noise if you don't care about the shrinking/growning number.
