Add ability to disable auto double quotes matching

[pbouffard]

This creates a workaround for #334. On Julia 1.10 and later the default is to disable OhMyREPL's matching of string literal delimiters (a.k.a double quotes ") , and this can be manually done on any Julia version with enable_autocomplete_string_literals(false), which is exported as with the existing enable_autocomplete_brackets.

I hope this pull request will be processed very soon since this is a good idea. I just want to disable the autocompletion of " mark but want to keep the autocompletion of brackets!

Just want to comment on the possibility of adding an option to disable autocompletion of single quotes (') as well. I have found myself typing ' for adjoint and having to delete the additional one given by autocompletion. It would be useful when creating a Char like 'a' but this happens less frequently than adjoint.

I am not sure if this needs to be an option. I would rather have it disabled by default and reduce configuration complexity.
