[BUG] Calling `.ToString()` on a `BsonValue` constructed from a `string[]` throws a `NullReferenceException`

[Cryptoc1]

Version v5.0.21, on net9.0

Describe the bug When constructing a BsonValue from an array of strings, calling .ToString() throws a NullReferenceException.

Code to Reproduce

var tags = ["hello", "world"];

var value = new BsonValue(tags);

// THROWS!
value.ToString();

Expected behavior .ToString() should return the string representation of the array.

Screenshots/Stacktrace

Hello! Thank you for bringing this up! What is the string representation you would expect here?
