Surface sensitive pattern as a configurable option

Description of the new feature/enhancement

we currently have this regex pattern hardcoded & this could be useful for further extensibility going forward.

PSReadLine/PSReadLine/History.cs

Lines 116 to 118 in e9122d3

	private static readonly Regex s_sensitivePattern = new Regex(
	"password|asplaintext|token|apikey|secret",
	RegexOptions.Compiled | RegexOptions.IgnoreCase);

Therefore it would be great to surface extensibility of this via either

1. fully configurable option with this pattern as the default setting
2. setable property for addtional patterns to match

2 I feel is a better & more secureminded implementation going forward & would enable users to manage asks like #4077 (which we perhaps could pull into the default's as part of this enhancement
