Scary error message with build that doesn't affect the build

[mooreds]

When I upgraded the versions of semver, vite and @babel/core per dependabot, we start seeing errors in the build:

https://github.com/FusionAuth/fusionauth-site/actions/runs/5697466455/job/15444222535

Error: R] Invalid command: on-resolve [plugin JavaScript plugins]

    node_modules/esbuild/lib/main.js:734:12:

  The plugin "JavaScript plugins" was triggered by this import

These don't appear to actually affect the build, and are because of vite components. I was able to change an article and have it stick, and the build doesn't fail.

Apparently if you upgrade to the latest version as of around May 4, the problem goes away: withastro/astro#6631

We're a ways behind astro (2.9.x is the latest, we're on 2.0.x): https://github.com/withastro/astro/releases and I tried to upgrade to 2.9.6, but got an error I couldn't figure out how to fix.
