Backports #24550.
Adjusts test to expect that didChangeWatchedFiles is *not* registered if
client `capabilities` is nil (as it's not enabled by default for v0.9).
fix(lsp): don't register didChangeWatchedFiles when capability not set
Some LSP servers (tailwindcss, rome) are known to request registration
for `workspace/didChangeWatchedFiles` even when the corresponding client
capability does not advertise support. This change adds an extra check
in the `client/registerCapability` handler not to start a watch unless
the client capability is set appropriately.
