linked page "bug report" doesn't exist

[Presskopp]

In \wp-includes\ms-load.php we have:

Read the <a href="%s" target="_blank">bug report</a> page. Some of the guidelines there may help you figure out what went wrong.

The linked page is ​https://wordpress.org/support/article/debugging-a-wordpress-network/

Patch using "Debugging a WordPress Network" as title for the link

[SergeyBiryukov]

Good catch, that line has some history:

• Introduced 14 years ago in ​mu:616, linking to ​https://mu.trac.wordpress.org/wiki/DebuggingWpmu.
• URL updated in ​mu:1177 to ​https://codex.wordpress.org/Debugging_WPMU. That link did (and still does) have some bug reporting guidelines for WPMU.
• Merged to WordPress core in [12602].
• URL updated to the current article in [15330], but the link text was not changed.
• URL switched from Codex to HelpHub in [45674].

In 47914:

Networks and Sites: Update the link text for "Debugging a WordPress Network" support article in ms_not_installed().

Props Presskopp.
