[BUG][vscode-extension] 404 on Changelog Release Notes Link

### Have you tried to resolve this issue yourself first?

- [x] I confirm I have gone through the above steps and still have an issue to report.

### Bug Description

The changelog link that opens in both the visual studio marketplace site and on VSCode is leading to a 404.

### Output / Logs

```shell

```

### Steps To Reproduce

1. Navigate to https://marketplace.visualstudio.com/items/salesforce.sfdx-code-analyzer-vscode/changelog or click on "CHANGELOG" on VSCode
2. Click on the [Salesforce Code Analyzer Release Notes](https://developer.salesforce.com/docs/platform/salesforce-code-analyzer/guide/release-notes.md) link.
3. 404 on this page

I think the link should be: https://developer.salesforce.com/docs/platform/salesforce-code-analyzer/guide/release-notes.html (.html instead of .md)

Search the repository for the Salesforce Code Analyzer Release Notes URL ending in .md and identify where the VSCode extension's changelog link is defined. Replace the broken target with the reported .html URL, then verify that the link from both the Visual Studio Marketplace changelog and VSCode resolves successfully.
