x/tools/gopls: umbrella for marker test flakes

[gopherbot]

#!watchflakes
default <- pkg == "golang.org/x/tools/gopls/internal/test/marker" && test ~ `^Test/.+txt$`

Issue created automatically to collect these failures.

Each time this issue gets notified of a new flake, create a specific issue for its underlying cause (e.g. a particular OS/ARCH combo amd tell-tale failure message) using a post rule so that new flakes are diverted there. (adonovan, Jun 2026)

Example (log):

Widened the pattern here to catch all Test/*.txt failures, otherwise watchflakes defaults to creating too many individual ones. (If their failure modes end up being different, they can be split up as needed.)
