goreleaser: Fix broken signing

[radeksimko]

This is to apply a patch similar to #474 which should address the following failure observed during release:

 • signing artifacts
      • signing                   cmd=[gpg -u *** --output dist/terraform-ls_0.16.0_SHA256SUMS.sig --detach-sign dist/terraform-ls_0.16.0_SHA256SUMS]
      • signing                   cmd=[gpg -u *** --output dist/terraform-ls_0.16.0_SHA256SUMS.***.sig --detach-sign dist/terraform-ls_0.16.0_SHA256SUMS]
      • gpg: signing failed: Inappropriate ioctl for device
 cmd=gpg
      • gpg: signing failed: Inappropriate ioctl for device
 cmd=gpg
      • gpg: signing failed: Inappropriate ioctl for device
 cmd=gpg
      • gpg: signing failed: Inappropriate ioctl for device
 cmd=gpg
   ⨯ release failed after 867.67s error=sign: gpg failed

Like #474 I'm going to merge this PR also now (without review) to try unblocking a release which is due, but post-merge reviews are welcomed.
