The key part of this patch is to fix the following sentence where hard to understand:

We also release for old uri gem with Ruby releases. Please use them if you need to only security fix.

I need to ask the original author to confirm the intention.

The `uri` gem version 0.10.1, 0.10.2, 0.11.0, 0.12.0, and all versions 0.10.0 and prior are vulnerable for this vulnerability.

* For Ruby 2.7 users: URI 0.10.0.1
* For Ruby 3.0 users: URI 0.10.2
* For Ruby 3.1 users: URI 0.11.1
* For Ruby 3.2 users: URI 0.12.1
## Recommended action

You can use `gem update uri` to update it. If you are using bundler, please add `gem "uri", ">= 0.12.1"` to your `Gemfile`.
We recommend to update the `uri` gem to 0.12.1. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead:

* For Ruby 2.7: Update to `uri` 0.10.0.1
* For Ruby 3.0: Update to `uri` 0.10.2
* For Ruby 3.1: Update to `uri` 0.11.1
* For Ruby 3.2: Update to `uri` 0.12.1

You can use `gem update uri` to update it. If you are using bundler, please add `gem "uri", ">= 0.12.1"` (or other version mentioned above) to your `Gemfile`.
