Update docs for Streamlit 1.62.0 release

[lukasmasuch]

Summary

• Add 1.62.0 release notes covering streamlit.typing, wrap control, text input types, date/datetime input rebuilds, and breaking changes (st.cache removal and st.pyplot figure requirement).
• Generate API docstrings for Streamlit 1.62.0, including DataEditorState, and update generate.py now that st.cache is gone.
• Document the st.cache removal in the caching guide, and add two Community Cloud example apps for the new wrap=False examples.

Test plan

• Spot-check the 1.62.0 section on /develop/quick-reference/release-notes and /develop/quick-reference/release-notes/2026.
• Confirm API pages pick up new parameters (wrap, validate, st.text_input types) and DataEditorState on st.data_editor.
• Confirm the caching migration section no longer says st.cache will remain.
• Deploy the new example apps (table below), then confirm the Cloud embeds on st.columns and st.container load.

App	Deploy link	GitHub file	Subdomain
st.columns wrap=False thumbnail row	Deploy	layout.columns_wrap_false.py	doc-columns-wrap-false
Horizontal st.container toolbar (wrap=False)	Deploy	layout.container6.py	doc-container6

• This new ## heading makes the existing ### Configuring columns heading a child of Data editor state, so the column-configuration section is nested incorrectly in the page outline. Please make Configuring columns a peer ## section, as in dataframe.md (which places its state and configuration sections at the same level).

## Data editor state

python/generate.py:552

• Historical regeneration also runs against pre-1.62 releases, where streamlit.cache is still present. With this guard removed, the legacy st.cache function is sent through member._decorator, but it is not one of the cache API objects that exposes that attribute, so generation fails before writing that version's existing st.cache entry. Keep a version-safe exclusion so 1.62 can omit the removed attribute while older versions still generate.

            # Replace the member with its decorator object
