Move section on indented strings after string interpolation (#1030)

Proposing to move the "_Indented strings_" section after "_String interpolation_" because I think it fits better there logically. Also added a note that string interpolation works in indented strings as well.

+### Indented strings
+
+Also known as “multi-line strings”.
+
+The Nix language offers convenience syntax for character strings which span multiple lines that have common indentation.
+
+Indented strings are denoted by *double single quotes* (`'' ''`).
+
+Example:
+
+```{code-block} nix
+:class: expression
+''
+multi
+line
+string
+''
+```
+
+```{code-block}
+:class: value
+"multi\nline\nstring\n"
+```
+
+Equal amounts of prepended white space are trimmed from the result.
+
+Example:
+
+```{code-block} nix
+:class: expression
+''
+  one
+   two
+    three
+''
+```
+
+```{code-block}
+:class: value
+"one\n two\n  three\n"
+```
+
+:::{note}
+Indented strings also support [string interpolation](string-interpolation).
+For details check the [documentation on string literals in the Nix language](https://nix.dev/manual/nix/2.24/language/syntax#string-literal).
