Match path nodes with method on snippet generation

[andrueastman]

This PR updates the snippet generation logic to fail in the event at a path is found but the requested http method does not exist in the metadata to prevent the generation of methods that do not exist in snippets.

Changes have been benchmarked with the dev branch in the pipeline runs at the links below.

In summary, snippets generated will reduce by about 1% as summarized in the table below from the above runs,

Title	Current rate	New rate	Change
V1 Go/C#	92.59%	91.63%	0.91%(23 snippets)
Beta Go/C#	91.15%	89.43	1.71% (63 snippets)

Note
Pass rates in compilation stages will therefore go up due to the failed compilation snippets now not being generated.
