feat: Add *gin.Context Filter parameter

Issue: https://github.com/open-telemetry/opentelemetry-go-contrib/issues/3070 last PR status: https://github.com/open-telemetry/opentelemetry-go-contrib/pull/4444

This PR seems unfinished (the GinFilter isn't used, the WithGinFilter method accepts a Filter, not a GinFilter and there are no tests). I'm moving it to draft. Feel free to undraft once you are finished.

@dmathieu Please review the changes, I have added the filter with test.

[dmathieu]

Did you run those tests? The filter exists, but isn't used anywhere. The code is also showing indentation issues that will fail linting.

Note : I'm not sure this is a good solution. @hanyuancheung, what do you think?

[rehanpfmr]

@dmathieu Please refer to https://github.com/open-telemetry/opentelemetry-go-contrib/pull/4444, the solution was recommended here. I'm looking at the Test for "TestWithGinFilter" is currently failing.

[rehanpfmr]

@dmathieu, Can you please review? The test with 'make build' seems to be passing.

Since this is changing the public API, I would like @hanyuancheung's opinion as code owner.
