Migrate callout syntax to Redocly format

[mDuo13]

This was originally scripted as part of #2259 but for some reason the script stopped working or missed a bunch of instances.

Example:

Before / old syntax:

**Note:** Any Offer in the DEX that would exchange two tokens can use XRP as an intermediary currency in a synthetic order book. The XRPL DEX automatically uses this bridging technique to improve exchange rates and liquidity when doing so is cheaper than trading token-to-token.

After / new syntax:

{% admonition type="info" name="Note" %}
Any Offer in the DEX that would exchange two tokens can use XRP as an intermediary currency in a synthetic order book. The XRPL DEX automatically uses this bridging technique to improve exchange rates and liquidity when doing so is cheaper than trading token-to-token.
{% /admonition %}

Both old and new use 4 color-coded categories of callout, but the names are different. In the old syntax, the bolded intro word acts as the title of the callout and also identifies the callout severity. In the new syntax, the visible title and color are set separately.

Color	Old Name (en)	Old Name (ja)	New Type
Green	Tip	ヒント	success
Blue	Note	注記	info
Yellow/Orange	Caution	注意	warning
Red	Warning	警告	danger

When migrating, the old name should go into the name= parameter and the corresponding new type should go into the type= parameter.
