refactor: update SVGO configuration for compatibility with SVGO 3

- Modified the SVGO configuration to align with SVGO 3 standards, replacing the old plugin format with the new preset-default structure.
- Adjusted the plugins list in plugins.js to ensure proper integration of the updated svgoconfig.
- This change enhances image optimization while maintaining compatibility with the latest SVGO version.

+/**
+ * SVGO 3+ config for imagemin-svgo / svgo-loader.
+ *
+ * Format: SVGO 3 rejects the v2 style `{ cleanupAttrs: true }` (no `name` on plugin objects).
+ *
+ * Why not list every plugin like the old file?
+ * - SVGO 3 expects either named plugins or `preset-default`, which bundles most optimizers
+ *   (cleanupAttrs, removeComments, convertPathData, mergePaths, etc.) in a maintained order.
+ *   Duplicating that full list in v3 `{ name, params }` form would be long and redundant.
+ * - Reference: https://svgo.dev/docs/preset-default/
+ *
+ * Mapping from the previous v2 `{ plugin: boolean }` list:
+ * - `true` on a built-in → usually covered by `preset-default` (see link above).
+ * - `false` falls into two cases in SVGO 3:
+ *   (A) Plugin is part of `preset-default` → turn it off with `params.overrides`
+ *       (e.g. `removeViewBox: false` below — removeViewBox runs inside the preset by default).
+ *   (B) Plugin is optional / not in the preset → do not list it; SVGO only runs plugins you
+ *       declare. So “false” in v2 = omit the plugin name here.
+ *       Examples from the old config:
+ *       - removeDimensions: https://svgo.dev/docs/plugins/removeDimensions/ — optional; not in
+ *         `preset-default`; we omit it so width/height stay (unless you add `'removeDimensions'`).
+ *       - removeRasterImages: https://svgo.dev/docs/plugins/removeRasterImages/ — optional;
+ *         not in `preset-default`; we omit it so embedded rasters are kept.
+ * - Extra plugins the old list enabled but preset does not include:
+ *   `convertStyleToAttrs`, `prefixIds` — listed explicitly below (sprites / ID stability).
