Remove remaining web.config references in translation files

[nul800sebastiaan]

so it will fallback to the correct English text

Fixes #11191

Since we can't keep #11191 open forever, the suggestion to just fallback to English is a good one, that's been done in this PR.

The following keys were removed in each file, if found in that file:

• databaseErrorWebConfig
• databaseNotFound
• licenseText
• theEndInstallFailed
• httpsCheckConfigurationRectifyNotPossible
• httpsCheckConfigurationCheckResult
• smtpMailSettingsNotFound
• smtpMailSettingsHostNotConfigured
• smtpMailSettingsConnectionFail

Note: this has been a completely manual job since I wanted to prevent reformatting all the xml files, which would be a noisy and unreadable PR. I validated all the XML files in an online validator to make sure I didn't introduce problems by not fully removing the complete <key /> elements.

FWIW, it looks like only the following keys are in active use:

• httpsCheckConfigurationRectifyNotPossible
• httpsCheckConfigurationCheckResult
• smtpMailSettingsNotFound
• smtpMailSettingsHostNotConfigured
• smtpMailSettingsConnectionFail

LGTM all parse well.
