Bumps handlebars from 4.7.6 to 4.7.7.

Changelog

Sourced from handlebars's changelog.

v4.7.7 - February 15th, 2021

• fix weird error in integration tests - eb860c0
• fix: check prototype property access in strict-mode (#1736) - b6d3de7
• fix: escape property names in compat mode (#1736) - f058970
• refactor: In spec tests, use expectTemplate over equals and shouldThrow (#1683) - 77825f8
• chore: start testing on Node.js 12 and 13 - 3789a30

(POSSIBLY) BREAKING CHANGES:

• the changes from version 4.6.0 now also apply in when using the compile-option "strict: true". Access to prototype properties is forbidden completely by default, specific properties or methods can be allowed via runtime-options. See #1633 for details. If you are using Handlebars as documented, you should not be accessing prototype properties from your template anyway, so the changes should not be a problem for you. Only the use of undocumented features can break your build.

That is why we only bump the patch version despite mentioning breaking changes.
