Description

It is currently not possiblt to npm install without --force in htmx-kitchensink starter (and presumably in htmx-base and htmx-base-ts) as well.

npm install fails with:

npm error code ERESOLVE
npm error ERESOLVE unable to resolve dependency tree
npm error
npm error While resolving: htmx-kitchensink@undefined
npm error Found: @kitajs/[email protected]
npm error node_modules/@kitajs/html
npm error   @kitajs/html@"^3.1.2" from the root project
npm error
npm error Could not resolve dependency:
npm error peer @kitajs/html@"^4.2.5" from @kitajs/[email protected]
npm error node_modules/@kitajs/ts-html-plugin
npm error   peer @kitajs/ts-html-plugin@">=1.3.3" from @kitajs/[email protected]
npm error   node_modules/@kitajs/html
npm error     @kitajs/html@"^3.1.2" from the root project
npm error
npm error Fix the upstream dependency conflict, or retry
npm error this command with --force or --legacy-peer-deps
npm error to accept an incorrect (and potentially broken) dependency resolution.

I'm guessing that the issue lies within @kitajs/html which requires @kitajs/ts-html-plugin@>=1.3.3 and therefore a 4.x version of @kitajs/ts-html

Expected Behavior

npm install correctly installs the dependencies
