Fix regex for the json-file logger opts in overview.md
The regex used to describe the max-file and max-size logging options for the json-file logger were incorrect. The regexes would only match a single character (a digit or a literal +). Instead the regexes should match 1 or more digits. The character class for the units of the max-size also included a pipe which meant that the regex would match 1| instead of only matching 1m, 1k, and 1g.
