Migrate Commons Lang from 2 to 3 and StringEscapeUtils to Commons Text

io.jenkins.tools.pluginmodernizer.MigrateCommonsLang2ToLang3AndCommonText

Migrate Commons Lang from 2 to 3 and StringEscapeUtils to Commons Text.

This pull request upgrades Apache Commons Lang 2 to Apache Commons Lang 3. Additionally, if the plugin uses StringEscapeUtils from Apache Commons Lang, it will be migrated to use Apache Commons Text instead.
The Apache Commons community recommends using Apache Commons Text for string escaping operations, as it offers a more focused and feature-rich API for text processing.

What's Changed?

• Migrated from deprecated/EOL Apache Commons Lang 2 to Commons Lang 3.
• If applicable: Transitioned from deprecated/EOL StringEscapeUtils in Apache Commons Lang to Commons Text.
