[pbs-devel] [PATCH proxmox-backup 1/2] notifications: templates: adapt to whitespace handling changes with new handlebars version

[Lukas Wagner]

Handlebars 4.1 changed how whitespace is trimmed when using the `~`
operator in helpers/variables in order to be closer to the canonical
JavaScript handlebars implementation. These changed impacted how some of
our notification templates were rendered. This commit aims to restore
the initial appearance.
