Update Wycheproof eddsa_test to v1 (renamed to ed25519_test)

[Sajjon]

Update Wycheproof testvector eddsa_test v0 to eddsa_test v1 (renamed to ed25519_test).

Checklist

• I've run tests to see all new and existing tests pass
• I've followed the code style of the rest of the project
• I've read the Contribution Guidelines
• I've updated the documentation if necessary

If you've made changes to gyb files

• I've run .script/generate_boilerplate_files_with_gyb and included updated generated files in a commit of this pull request

Motivation:

We ought to use as many and as up to date test vectors as possible. Wycheproofs v0 were created 4 years ago and were due some upgrade.

Modifications:

• Replaced the v0 with the v1 version.
• Renamed the file from eddsa_test to ed25519_test since Wycheproof renamed the file.
• Updated one single JSON key, since Wycheproof changed the JSON data format key -> publicKey

Result:

Number of tests is now 150 instead of v0's test count of 145.
