Add .gitattributes to configure Linguist for Protocol Buffer files

adding .gitattributes

[jt-nti]

I think that this PR is related to https://github.com/github-linguist/linguist/blob/main/docs/overrides.md but I'm not sure why it's necessary. As far as I know, there aren't any *.protobuf files, and the following search seems to find the files I would expect...

https://github.com/search?q=repo%3Ahyperledger%2Ffabric-protos++language%3A%22Protocol+Buffer%22&type=code

Please could you explain what the new .gitattributes file is intended to achieve? If there is a good reason, I think it needs updating to match the files/directories found in this repository, and you would need a DCO sign off on your commit.

Thanks.

Hey @jt-nti,

The reason is I don't think the.proto files will show up in the repository because the linguist is not able to understand it. I use this exact same .gitattributes configuration in our internal repos to highlight protocol buffers and here's a link that this repository contains that.

https://github.com/hyperledger/fabric-protos/blob/main/gateway%2Fgateway.proto

I know it's a small PR but it's just better visibility for people who are looking at protobuf for the first time.

Thanks.

Ah, I see, you want Protocol Buffer to show up in the repository stats...

In that case, I think you only need this... https://github.com/hyperledger/fabric-protos/pull/280/changes

I'd be happy to approve your PR if you remove the other changes.

Thanks for adding the DCO signoff.
