Fix bug where colon is replaced by "%3A" #196

[dynamiccookies]

This fixes the issue where the search is not automatically populating on Radarr and Sonarr:

"When opening Radarr/Sonarr from the respective icon on IMDb & TMDB, the search page is opened but the search field is not populated. The IMDB/TMDB reference appears in the url."

What should say 'imdb:tt0795176' is instead coming through as 'imdb%3Att0795176'.

This is because the searchTerm is being URI encoded:

sonarr-radarr-lidarr-autosearch-browser-extension/src/content/js/content_script.js

Line 1513 in b56ef30

let searchUrl = site.domain.replace(/\/$/, '') + site.searchPath + encodeURIComponent(searchTerm).replace(/\./g, ' ');

This fix adds .replace(/%3A/g, ':') to encodeURIComponent(searchTerm).replace(/\./g, ' ') so '%3A' is replaced with a colon again.

Close #196
