Autobuild with working-directory doesn't always work

比较附加的 working.log 和 not-working.log，先从 autobuild.sh 如何接收和使用 working-directory 值开始。使用位于 monorepo 子目录下的 solution 重现 workflow，并验证 autobuild 始终选择该目录，而不是 github.workspace；现有的 manual-build workaround 提供了比较依据。

Hi,

I'm working in a monorepo setup and was using the following CodeQL setup to run CodeQL on a sub directory
`

- name: Initialize CodeQL
  uses: github/codeql-action/init@v3
  with:
    languages: ${{ matrix.language }}
    build-mode: ${{ matrix.build-mode }}
    config: |
      queries:
        # See https://docs.github.com/en/code-security/code-scanning/creating-an-advanced-setup-for-code-scanning/customizing-your-advanced-setup-for-code-scanning#using-queries-in-ql-packs
        - name: Security and maintainability
          uses: security-and-quality
              
- if: matrix.language == 'csharp'
  name: Build solution
  uses: github/codeql-action/autobuild@v3
  with:
    working-directory: code/<redacted>      

- name: Perform CodeQL Analysis
  uses: github/codeql-action/analyze@v3
  with:
    category: "/language:${{matrix.language}}"`

Initially, in some runs, the autobuild step correctly picked up a .sln file from the specified working directory but since yesterday, in several runs, the option can be seen to be overriden by the autobuild script and it uses the github.workspace directory i.e., the root of the monorepo.

From the logs, I can see a difference in the environment variables and how the autobuild.sh is run

not-working.log
working.log

I'm using manual build as a workaround for now.
