IURL anchor links force url

[jdarwood007]

Description

When you use iurl to link to a anchor bbc in a post, it incorrectly will force the entire url into the post.

Steps to reproduce

1. Create new post.
2. Use contents:

[iurl="#db_query"]$smcFunc['db_query'][/iurl]

TEST

[anchor=db_query]$smcFunc['db_query'] (identifier, query, values, connection)[/anchor]

3. Post the message
4. Edit the message
5. Results show the iurl now contains $scripturl=action=post.....#anchor]

Environment (complete as necessary)

• Version/Git revision: latest
• Database Type: N/a
• Database Version: N/a
• PHP Version: PHP 8.1 and PHP 8.2

Noticed on sm.org and confirmed in my dev env.

Seems to be because we pass it through encodeURI()
