feature: 🍺 Support for Continue statement

[shivasurya]

Description:

This pull request introduces support for parsing and handling continue statements in the code graph. The changes include updates to the core parsing logic, graph construction, and associated test cases.

Parsing and Graph Construction Enhancements:

• Added ContinueStmt field to the Node struct in sourcecode-parser/graph/construct.go to handle continue statements.
• Implemented logic to parse continue statements in sourcecode-parser/graph/construct.go and add them to the code graph.
• Created a new function ParseContinueStatement in sourcecode-parser/graph/java/parse_statement.go to parse continue statements from the AST.

Test Case Additions:

• Updated TestBuildGraphFromAST in sourcecode-parser/graph/construct_test.go to include continue statements in test cases. [1] [2]
• Added TestParseContinueStatement in sourcecode-parser/graph/java/parse_statement_test.go to validate the parsing of continue statements.
• Added TestContinueStmt in sourcecode-parser/model/stmt_test.go to test various methods of the ContinueStmt struct.

Model and Query Updates:

• Introduced ContinueStmt struct and interface in sourcecode-parser/model/stmt.go to represent continue statements.
• Added methods to handle continue statements in sourcecode-parser/graph/query.go, including GetContinueStmt and updates to generateProxyEnv. [1] [2] [3] [4]

Checklist:

• Tests passing (gradle testGo)?
• Lint passing (golangci-lint run this requires golangci-lint)?
