docs: use json5 for bare object literal code blocks (#54107)

* docs: use json5 for bare object literal code blocks

Several docs code blocks contain only a bare object literal (an example
return value or options object) but are tagged as `js`. As JavaScript,
`{ key: value, ... }` on its own is a block statement, not an object, so
standard/ESLint reports "Parsing error: Unexpected token :" on most of
them; they only lint today because @electron/lint-roller special-cases
them with a regex that wraps orphan `{...}` blocks in parens before
linting. The blocks are valid JSON5, so tag them as such and drop the
`<!-- eslint-skip -->` comments that preceded them, which nothing in the
current tooling honors.

* docs: use json5 for bare array menu template blocks

The three menu template examples in docs/tutorial/menus.md are bare
array literals, not runnable JavaScript. Like the bare object literal
blocks in the previous commit, they are valid JSON5, so tag them as
such instead of `js`.

* docs: use json5 for bare literal blocks nested in blockquotes

The radio menu item example in the `[!TIP]` blockquote in
docs/tutorial/menus.md is a bare array literal tagged `js`; it was
missed earlier because the fence is prefixed with `> `. It is valid
JSON5 (including the trailing `//` comment), so tag it json5 like the
other bare literal blocks.
