Java: Improve weak crypto query

[jcogs33]

Description

Removes weak hash algorithms such as MD5 and SHA1 from java/weak-cryptographic-algorithm and adds these cases to java/potentially-weak-cryptographic-algorithm instead.

The removal of weak hash algorithms from java/weak-cryptographic-algorithm aligns with other languages, e.g. #11129.

Consideration

Let me know if there is any concern with changing the behavior of rankedInsecureAlgorithm instead of doing the exclusion for java/weak-cryptographic-algorithm directly in BrokenAlgoLiteral? I chose to do the exclusion in rankedInsecureAlgorithm since doing so automatically adds the weak hash cases to java/potentially-weak-cryptographic-algorithm due to this code.

Note that there were some overlapping results between the two queries for cases where a weak hash algorithm string literal is used as the default value in a getProperty call (e.g. the "MD5" value in this test case). In order to avoid duplicate results for these cases in the java/potentially-weak-cryptographic-algorithm query, I've added an exclusion to InsecureAlgoLiteral.

DCA alert changes look reasonable.
