+/**
+ * Reads the level of indentation of the first line and trims the identation for all the text by that amount.
+ *
+ * For example, for:
+ *
+ * ```json
+ *          {
+ *              "hello": "world"
+ *          }
+ * ```
+ *
+ * it results in:
+ *
+ * ```json
+ * {
+ *     "hello": "world"
+ * }
+ * ```
+ *
+ * This is meant to be used as a template string, where it allows the indentation of the template without affecting whitespace changes.
+ *
+ * @example const html = trimIndentation`\
+ *           <h1>Heading 1</h1>
+ *           <h2>Heading 2</h2>
+ *           <h3>Heading 3</h3>
+ *           <h4>Heading 4</h4>
+ *           <h5>Heading 5</h5>
+ *           <h6>Heading 6</h6>
+ *       `;
+ * @param strings
+ * @returns
