Hi and props on this great project :)

I'm trying to use a configuration file with lychee-action to improve the readability, as in, to not pollute the action with many arguments and I'm struggling to define a valid configuration file.

Having an updated lychee.example.toml would make it easier for everyone to use it.

Issues I found so far:

• Many command line parameters are missing
  • It seems to me (not a rust developer) that all command line parameters can be defined through the configuration file. Still it's not obvious what the variable names should be.
• The commented example #accept = "text/html" does not match the description. The example should be #accept = "503,403"
• The exclude_file = [] should have an example as it's not obvious (to me) that file paths must be quoted, as in, must be strings.
