Describe the bug

As you can see from the version information, I have Go 1.25.6 on my machine. Yet gopls was compiled with Go 1.25.5. I tried re-running "Go: Install/Update Tools" several times but it did not cause gopls to be upgraded to the new toolchain.

Steps to reproduce the behavior:

1. Install latest gopls with Go 1.25.5.
2. Upgrade to Go 1.25.6.
3. Run "Go: Install/Update Tools".
