Reconfigure lint rule w.r.t. quotes

We prefer single quotes by default, but still want to allow double
quotes in cases where that helps avoid quote-escaping, and also want
to allow template literals in cases where string interpolation is
used. For example:

    const a = 'xxx';  // ok
    const b = "xxx";  // not ok, should use single quotes
    const c = "xxx'xxx";  // ok, double quotes avoid an escape sequence
    const d = `xxx`;  // not ok, frivolous use of template literal
    const e = `xxx ${42}`;  // ok

Per https://github.com/eslint/eslint/issues/12976, setting
the `allowTemplateLiterals` option for the `quotes` lint rule to
`false` gives us the desired behavior.

Note that the above lint rules are auto-fixed when running the linter;
there should be no need to manually make any changes to appease the
linter.

Per review feedback, this patch also removes the following escape
sequences for printable non-ASCII symbols:

- U+00D7 → ×
- U+2026 → …
- U+2019 → ’
