It works fine with (electric-indent-mode -1) and

  :custom
  (go-ts-mode-indent-offset 4)

You setup looks not so optimal. Here is mine

(use-package go-mode
  :ensure t
  :mode "\\.go\\'"
  :preface
  (defun vd/go-lsp-start()
               (add-hook 'before-save-hook #'lsp-format-buffer t t)
               (add-hook 'before-save-hook #'lsp-organize-imports t t)
               (lsp-deferred)
               )
  :hook
  (go-ts-mode . vd/go-lsp-start)
  :bind
  (:map go-ts-mode-map
        ("RET" . newline-and-indent)
        ("M-RET" . newline)
        )
  :config
  (add-to-list 'exec-path "~/.local/bin")
  (setq lsp-go-analyses '(
                          (nilness . t)
                          (shadow . t)
                          (unusedwrite . t)
                          (fieldalignment . t)
                                       )
        lsp-go-codelenses '(
                          (test . t)
                          (tidy . t)
                          (upgrade_dependency . t)
                          (vendor . t)
                          (run_govulncheck . t)
                                       )
        )
)

(use-package go-tag
  :ensure t
)

(use-package godoctor
  :ensure t
)

You are doing it completely wrong

I use :custom a LOT. Config is so clean and short compare to default setup.

(use-package magit
  :ensure t
  :defer t
  :functions magit-status
  :custom-face
  (magit-diff-added ((t (:background "dark slate gray" :foreground "chocolate"))))
  (magit-diff-added-highlight ((t (:background "dark olive green" :foreground "gold"))))
  (magit-diff-removed ((t (:background "red" :foreground "#ffdddd"))))
  (magit-diff-removed-highlight ((t (:background "dark red" :foreground "navajo white"))))
  :custom
  (magit-diff-refine-hunk                'all)
  (magit-display-buffer-function         'magit-display-buffer-fullframe-status-v1)
  (magit-ediff-dwim-show-on-hunks        t)
  (magit-log-arguments                   '("--graph" "--color" "--decorate" "--show-signature" "--follow" "-n256"))
  (magit-log-margin-show-committer-date  t)
  (magit-log-remove-graph-args           '("--follow" "--grep" "-G" "-S" "-L"))
  (magit-todos-insert-after              '(bottom))
  :bind(
  ("C-x C-z" . magit-status)
  :map evil-normal-state-map
  ("gs"  . magit-status)
  )
)
