Linter lints old version when comparing diffs

**Describe the bug**
A clear and concise description of what the bug is.

**To Reproduce**
Steps to reproduce the behavior:
1. Create & **commit** the following workflow:
```yaml
# yaml-language-server: $schema=https://json.schemastore.org/github-workflow.json
name: Build

on:
pull_request:
branches:
- main

permissions:
contents: read

jobs:
build:
name: Build
runs-on: ubuntu-latest
outputs:
build_id: ${{ steps.build.build_id }}
steps:
- name: Checkout
uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1
with:
show-progress: false

- name: Build
id: build
shell: bash
run: |
echo "Building"
echo "build_id=12345" >> "$GITHUB_OUTPUT"

```
1. Notice the linting warning on `${{ steps.build.build_id }}`: `Context access might be invalid: build_id`.
1. Delete the following lines, save but do NOT commit:
```yaml
outputs:
build_id: ${{ steps.build.build_id }}
```
1. In the diff window compare the changes
1. (BUG 1) (while diff is open) Notice the LEFT window showing the linting warning, which also shows up under 'PROBLEMS'


1. (while diff is open) Double click the warning under problems and notice it opens a locked (denoted the padlock next to the name) version of the previous, unedited version of `build.yaml`.


1. Close the diff & locked old version of `build.yaml`
1. (BUG 2) Notice the linting error is still there under 'PROBLEMS'


1. (BUG 2 related) When double clicking linting warning it opens up the same locked (denoted the padlock next to the name) version of the previous, unedited version of `build.yaml`.
1. (BUG 1) Now when hitting 'CTRL+P' to switch between files there are 2 entries for `build.yaml` which are indistinguishable, yet refer to different versions:


**Expected behavior**
Only errors on the new version are reported.

**Screenshots**
See reproduction

**Extension Version**
`v0.26.2`
