Make go_deps restarts less costly

@linzhp Could you test whether this reduces the runtime of the extension?

[linzhp]

Still got 11 go_deps, the longest became:

    {"cat":"bazel module processing","name":"evaluate module extension: @@gazelle~0.34.0//:extensions.bzl%go_deps","ph":"X","ts":7769016,"dur":283072,"pid":1,"tid":306},

Before this PR, the longest was:

    {"cat":"bazel module processing","name":"evaluate module extension: @@gazelle~0.34.0//:extensions.bzl%go_deps","ph":"X","ts":7541933,"dur":140592,"pid":1,"tid":288},

So it doesn't reduce the runtime.

@linzhp Could you also check the sun of the durations? This PR making it worse is pretty unexpected... We can't do anything about the number of restarts unfortunately.

All go_deps restarts run sequentially, so I get the timestamp of the last instance plus its duration subtracted by the timestamp of the first instance

Before this PR, I got 891225; after this PR, I got 1557146
