fix(packages): update package definitions to be compatible with latest straight.el

A recent change (https://github.com/raxod502/straight.el/pull/558) to
straight.el's use-package integration led to some of my :straight
definitions throwing errors.

When overriding the package name, do not wrap the real name in parens,
for example:

    ;; bad (no longer works)
    (use-package helm-global-bindings
      :straight (helm))

    ;; good (worked before, still works)
    (use-package helm-global-bindings
      :straight helm)
