x/tools/gopls: remove the "allowImplicitNetworkAccess" setting

[findleyr]

Following up on #66860, this issue tracks removing the "allowImplicitNetworkAccess" setting. As stated on that issue:

We should not have settings that affect low level behavior like this, as such settings are inevitably insufficiently tested and hard to maintain. Gopls should work well with its default decisions about allowing network access

If you are here because you use this setting and received a warning that it will be removed, please explain why you use it!

@findleyr can I take this up?

@nikzayn sorry but this is really just a process issue, not a good candidate for contribution.

Change https://go.dev/cl/621877 mentions this issue: gopls/internal/settings: remove "allowImplicitNetworkAccess"

[francislavoie]

In my VSCode, I've been getting Invalid settings: setting option "allowImplicitNetworkAccess": this setting is deprecated error on startup for a while now (non-critical, but an annoyance). For the life of me, I can't figure out where to look to clear this up. I'd appreciate some help! 😅

Edit: Oh, that was confusing. It wouldn't show up in the VSCode settings GUI, but once I opened the settings.json is was in there. Now removed.
