deps: update

[ParkerOu]

Due to package deprecation, it has been replaced with a new package

1. vue-cli -> vite
2. xterm-addon-fit -> @xterm/addon-fit
3. xterm -> @xterm/xterm

After the update, four moderate-severity vulnerabilities were fixed.

If it's set up on a non-root path, such as https://my-domain/piping-ssh-web, you need to modify vite.config.mjs by adding base: '/piping-ssh-web/' to the defineConfig()

import { fileURLToPath, URL } from 'node:url';
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
import { createHtmlPlugin } from 'vite-plugin-html';

export default defineConfig({
  base: '/piping-ssh-web/', // add this line if needed
  plugins: [
    vue(),
    createHtmlPlugin({
      minify: true,
      inject: {
        data: {
          title: 'Piping SSH',
        },
      },
    }),
  ],
  esbuild: {
    target: 'es2015',
  },
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url)),
    },
  },
});

@nwtgck Could you help me check if the PR is OK?

@ParkerOu
Thank you for your pull request to update the dependencies! I appreciate your efforts to address package deprecation and security fixes. However, as the project maintainer, I feel it's important that I handle changes to the core dependencies and infrastructure myself. This allows me to thoroughly review the impact of the changes, ensure compatibility, and maintain the overall integrity of the project.
