feat(docs): add contributors & enhance AddonGallery components

[WRXinYue]

According to Xiaoyun's request, the addon author is now displayed in addons/gallery. In addition, some interactive search logic has been added to AddonGallery. More addons have been added to the documentation, and the valaxy-addon-git-log has been included to display the contributors to the documentation.

Adding an index.md file under each folder in the pages directory will prevent this error. This issue arises due to the following code:

<RouterView v-slot="{ Component }">
  <component :is="Component">
    <template #default>
      <div class="prose mx-auto w-full max-w-4xl">
        <h2 :id="t('post.contributors')">
          <a :href="`#${t('post.contributors')}`" class="header-anchor" />
          {{ t('post.contributors') }}
        </h2>
        <GitLogContributor />
      </div>
    </template>
  </component>
</RouterView>

Using RouterView directly does not cause build errors, and this issue might be related to #358.

CI is failed, some problems need to check.
