feat: decided to use "tera" at the end as template engine

- Change dependency from `handlebars` to `tera` in Cargo.toml
- Remove unused shell variables and FZF colors configuration in `colors.sh`
- Replace `Handlebars` with `Tera` for template rendering in `templ.rs`
- Replace `BTreeMap` with `Context` for template data in `templ.rs`
- Use `tera.add_raw_template` instead of `handlebars.register_template_string` in `templ.rs`
- Use `tera.render` instead of `handlebars.render` to render the template in `templ.rs`
