OSV.dev API doesn't respect .nuspec package id case-insensitivity

[Franck-Boost]

Describe the bug
The .nuspec specification indicate that package id is case-insensitive. However, the OSV.dev API is case-sensitive for NuGet package id.

To Reproduce
Steps to reproduce the behaviour:

1. Calling the following don't return any vulnerabilities:

   curl -d \
     '{"package": {"name": "snowflake.Data", "ecosystem": "NuGet"}, "version": "2.1.2"}' \
     "https://api.osv.dev/v1/query"
   

2. Calling the following return three vulnerabilities:

   curl -d \
     '{"package": {"name": "Snowflake.Data", "ecosystem": "NuGet"}, "version": "2.1.2"}' \
     "https://api.osv.dev/v1/query"
   

Expected behaviour
The OSV.dev API respect the .nuspec specification case-insensitivity for package id. Invoking the API for NuGet package id snowflake.Data should return the same results as for Snowflake.Data for a given version.
