This PR adds syntax highlighting and indentation support for Handlebars (*.hbs) templates and Glimmer (*.gjs/*.gts) files. While Vim already detected these filetypes, it lacked the syntax and indentation definitions needed for proper editing.

Changes:

Handlebars Support:
- Added new runtime/syntax/handlebars.vim with syntax highlighting for Handlebars templates
- Added new runtime/indent/handlebars.vim with better indentation rules for Handlebars
- Added a missing filetype test case for .hbs files
Glimmer Support:
- Added new runtime/syntax/glimmer.vim that combines JavaScript/TypeScript syntax with Handlebars syntax
- Properly handles <template> blocks within Glimmer files

The Handlebars code is adapted from an external project with permission from the original author under the MIT license (properly attributed in both files). This enhances Vim's support for Ember.js and other frameworks that use these template formats.

I am unable to understand the current test failures. They appear to be network issues concerning Linux OS packages unrelated to the runtime files added in this PR?
