keepRemoved doesn't work with specified array of patterns

[Mormen]

🐛 Bug Report

I'm using i18next-parser and I would like to remove unused keys, but exclude some patterns.

To Reproduce

• With boolean value, it works. But when I try to use regex pattern, it fails.
  keepRemoved: ["\binterval\w*\b"],

• It throws error
  [error] TypeError: pattern.test is not a function

From docs
keepRemoved: false, // Keep keys from the catalog that are no longer in code // You may either specify a boolean to keep or discard all removed keys. // You may also specify an array of patterns: the keys from the catalog that are no long in the code but match one of the patterns will be kept. // The patterns are applied to the full key including the namespace, the parent keys and the separators.

Your Environment

• runtime version: i.e. node v16.15.1
• i18next version: i.e. 20.3.2
• os: Linux

Try using a regular expression literal instead of putting your pattern inside a string, e.g.
keepRemoved: [/\binterval\w*\b/]
