[transloco-validator] check for missing curly brace

[Serrulien]

Is your feature request related to a problem? Please describe.

In one of my translation, there is a missing curly brace: "manage-space-form.default-title-for-slot": "Created by { creatorFirstName }} {{ creatorLastName }}".

So far transloco-validor doesn't check for such mistakes. The only way to find it is by the error logged at runtime :

ERROR
Object {
    expected: Array(10) [ {…}, {…}, {…}, … ]
    ​found: "}"
    ​location: Object { start: {…}, end: {…} }
    ​message: "Expected \"#\", \"{\", doubled apostrophe, end of input, escaped string, or plain char but \"}\" found."
    ​name: "SyntaxError"
    ​stack: ""
}

The error message is quite cryptic and you can't tell at first glance that it is due to an invalid translation message.

Describe the solution you'd like

We would like to assert at build time that our translation files contains messages that will be correctly parsed. One of the checks could search for missing curly braces.
