contrib/(github and gopkg)/gorm: Mark as deprecated

[ajgajg1134]

What does this PR do?

Mark these old gorm packages as deprecated

Motivation

Make it clear to customers who are looking to use gorm which version of gorm they should use.
For details:
Gorm originally was hosted on gopkg.in, it was then moved to github.com where new versions were hosted.
Eventually there was a "v2" release AND it moved to a new org on github at gorm.io, during this move they were able to keep the "V1" tag because the import path itself changed (even though technically it's a new v2 version with breaking changes described here)

Note that the old v1 github version has not had a release since 2020 so customers should almost certainly NOT be using it anymore and there are documented CWEs*.

*To be fair, the documented CWE that I read doesn't actually seem like it's a vulnerability in Gorm and is really a mis-use of the API where users create a SQL injection attack (which I think is also equally possibly in database/sql) as described in this github comment

Reviewer's Checklist

• Changed code has unit tests for its functionality at or near 100% coverage.
• There is a benchmark for any new code, or changes to existing code.
• If this interacts with the agent in a new way, a system test has been added.

For Datadog employees:

• If this PR touches code that handles credentials of any kind, such as Datadog API keys, I've requested a review from @DataDog/security-design-and-guidance.
• This PR doesn't touch any of that.
