Update tera requirement from 1.15 to 2.3

[dependabot]

Updates the requirements on tera to permit the latest version.

Changelog

Sourced from tera's changelog.

2.3.0 (2026-08-26)

• Add State::{escape,autoescaping_enabled,escape_if_needed}
• Add StringInput to use for input/parameters that is safety aware and use it for built-in filters: this means you should need less | safe and that string safety is passed around correctly. Safety is dropped by filters where the changes depend on the content itself (truncate can cut anywhere) and preserved when they specify exactly what changes (trim, replace).
• Add escape filter that is safety aware (it will not escape an already safe string) and uses the current instance escape function
• Escaping included templates is now done base on where it's included rather than the included template itself: for example a .txt included in a .html will now be autoescaped if Tera autoescapes on .html.
• Fix double escape of filter/set blocks

2.2.0 (2026-08-20)

• Do not reserialize existing Value when serializing to a Value
• Error on content in children templates that would have been ignored
• Allows blocks inside if/elif/else again like in v1
• Allows the indentation character of the indent filter to be configured
• Add chained filter sections
