gopls/internal/regtest: update TestEditFile to use a modified buffer

In CL 267577, the fake editor was updated to automatically refresh
unmodified buffers with on-disk changes. This created a race in
TestEditFile, which asserts that on-disk changes are NOT reflected in
open buffers.

Fix this by inserting a trivial modification to the open buffer.  Also
make the test deterministic, so that it fails consistently without this
modification.
