Trailing Slash Appended to Asset Files in Docusaurus 3.3.2

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

We are attempting to upgrade to Docusarus 3.3.2, and we are noticing an interesting behavior with trailing slashes on asset files. We have by default the following baseURL and trailingSlash configuration

  baseUrl: "/",
  trailingSlash: true,

After the upgrade, if we do a docusarus serve we get a broken page that are missing assets. Upon closer inspection we noticed that asset files are specified with a / at the end. For example runtime-main.d2091a86.js/

It's strange that not all files have this behavior.

If we change the trailingSlash configuration to false then this issue goes away.

Reproducible demo

We have a PR in our public repo that can be used to test
spectrocloud/librarium#2839.

Just make sure you set the following env values before starting any server or build

ALGOLIA_APP_ID=1234567890
ALGOLIA_SEARCH_KEY=1234567890

Steps to reproduce

Upgrade to Docusarus 3.3.2 and set the configuration file to have the following baseURL and trailingSlash configuration

  baseUrl: "/",
  trailingSlash: true,

Expected behavior

We would expect asset files to not have an extra / at the end.

Actual behavior

Pages are loading with missing assets.

Self-service

😅 sorry for that, likely a regression introduced by #10090

I forgot serve might not just serve HTML files 😓

All good @slorber and thank you for validating what we seemed was a bit odd 😄
