Updated Handlebars to v4.7.9

[kevinansfield]

What

• bump ghost/core's explicit handlebars dependency from 4.7.8 to 4.7.9
• update the split helper and its unit test to use Ghost's frontend Handlebars runtime consistently when multiple handlebars copies are present

Why

Ghost core frontend helpers rely on SafeString constructor identity. If one helper creates SafeString values from a different handlebars module instance than another helper checks with instanceof, those values stop matching even though they look identical. Using the shared frontend Handlebars runtime keeps helper behavior consistent across dependency layouts.

Walkthrough

The changes standardize SafeString imports across helpers and tests in the frontend layer. Previously, some helpers and tests imported SafeString directly from the handlebars package. These changes update imports in the split helper and its test to use SafeString from a shared frontend runtime service instead. A clarifying comment was added to the match helper explaining this shared import approach. Additionally, the handlebars dependency in package.json was updated from version 4.7.8 to 4.7.9.
