[BUG] [search] wrong url for index.json with canonifyURLs = true

[mhagnumdw]

Describe the bug

if canonifyURLs = true is set in config.toml, baseURL is not used to get index.json. So the search doesn't work.

baseURL = "https://group.pages-gitlab.mydomain.com.br/techblog/"

Browser console: VM1586:1 GET https://group.pages-gitlab.mydomain.com.br/techblog/index.json 404 (Not Found)

Expected behavior

The search works with canonifyURLs = true and the baseURL is /something.

Changing from .RelPermalink to .Permalink solves:

FeelIt/layouts/partials/assets.html

Line 31 in 92084dc

{{- $config = dict "type" "lunr" "lunrIndexURL" .RelPermalink | dict "search" | merge $config -}}

Tested with canonifyURLs = true and canonifyURLs = false (hugo default).

I'm hesitant to proceed with a fix, as the Lunr JS repository hasn't shown any official activity since 2020. Given the lack of recent updates, it's unclear whether changes would be supported or maintained.
