[dependabot]

Bumps terser from 5.20.0 to 5.26.0.

Changelog

Sourced from terser's changelog.

v5.26.0

• Do not take the /*#__PURE__*/ annotation into account when the side_effects compress option is off.
• The preserve_annotations option now automatically opts annotation comments in, instead of requiring the comments option to be configured for this.
• Refuse to parse empty parenthesized expressions (())

v5.25.0

• Regex properties added to reserved property mangler (#1471)
• pure_new option added to drop unused new expressions.

v5.24.0

• Improve formatting performance in V8 by keeping a small work string and a large output string

v5.23.0

• When top_retain will keep a variable assignment around, inline the assignee when it's shorter than the name (#1434)
• Remove empty class static {} blocks.

v5.22.0

• Do not unsafely shorten expressions like a?.toString() when they're conditional.
• Avoid running drop_unused in nodes that aren't scopes. Fixes a rare crash.
• When 'module' is enabled, assume strict mode when figuring out scopes.

v5.21.0

• Do not inline functions that would be retained in the toplevel (as this would cause code duplication).
• Fix precedence of arrow function and ternary operator when formatting output.
