golangci-lint: Fix GCI warnings

[justaugustus]

Fixes needed for #122.

From https://golangci-lint.run/usage/linters/#gci:

linters-settings:
  gci:
    # DEPRECATED: use `sections` and `prefix(github.com/org/project)` instead.
    local-prefixes: github.com/org/project
    # Checks that no inline Comments are present.
    # Default: false
    no-inline-comments: true
    # Checks that no prefix Comments(comment lines above an import) are present.
    # Default: false
    no-prefix-comments: true
    # Section configuration to compare against.
    # Section names are case-insensitive and may contain parameters in ().
    # Default: ["standard", "default"]
    sections:
      - standard # Captures all standard packages if they do not match another section.
      - default # Contains all imports that could not be matched to another section type.
      - comment(your text here) # Prints the specified indented comment.
      - newLine # Prints an empty line
      - prefix(github.com/org/project) # Groups all imports with the specified Prefix.
    # Separators that should be present between sections.
    # Default: ["newLine"]
    section-separators:
      - newLine

local-prefixes is deprecated, so we use sections here instead.

Because of a few things:

• dependabot automatically updates golangci-lint-action versions
• the gci linter warning is something that would've been caught with a newer version of golangci-lint

I've also dropped the version configuration, so it will default to using the latest version of golangci-lint when running CI.
