<!-- Thanks for trying to help us make Apache Druid be the best it can be!
Please fill out as much of the following information as is possible (where
relevant, and remove it when irrelevant) to help make the intention and scope
of this PR clear in order to ease review. -->
This PR fixes #10259 .
### Description
The cause and solution has been discussed completely in the issue.
In this PR, parent class of `JsonReader` is changed from `TextReader` to
`InputEntityReader` to handle both pretty formatted JSON text and
line-delimited JSON based on the function provided by `ObjectMapper.readValues`
<!--
In each section, please describe design decisions made, including:
- Choice of algorithms
- Behavioral aspects. What configuration values are acceptable? How are
corner cases and error conditions handled, such as when there are insufficient
resources?
- Class organization and design (how the logic is split between classes,
inheritance, composition, design patterns)
- Method organization and design (how the logic is split between methods,
parameters and return types)
- Naming (class, method, API, configuration, HTTP endpoint, names of
emitted metrics)
-->
<!-- It's good to describe an alternative design (or mention an alternative
name) for every design (or naming) decision point and compare the alternatives
with the designs that you've implemented (or the names you've chosen) to
highlight the advantages of the chosen designs and names. -->
<!-- If there was a discussion of the design of the feature implemented in
this PR elsewhere (e. g. a "Proposal" issue, any other issue, or a thread in
the development mailing list), link to that discussion from this PR description
and explain what have changed in your final design compared to your original
proposal or the consensus version in the end of the discussion. If something
hasn't changed since the original discussion, you can omit a detailed
discussion of those aspects of the design here, perhaps apart from brief
mentioning for the sake of readability of this PR description. -->
<!-- Some of the aspects mentioned above may be omitted for simple and small
changes. -->
