Deprecate the support of language_tool_python

[joshiayush]

Description

Deprecate the support of language_tool_python for correcting template syntax; we don't need it anymore.

You can remove the following code:

inb/inb/linkedin/message/template.py

Lines 106 to 110 in 6341867

	self._enable_language_tool = grammar_check
	if self._enable_language_tool:
	import language_tool_python
	self._language_tool = language_tool_python.LanguageTool(
	language=DEFAULT_LANG)

Also,

inb/inb/linkedin/message/template.py

Lines 198 to 199 in 6341867

	if self._enable_language_tool:
	message = self._language_tool.correct(message)

Also, change the constructor's argument list by removing the grammar_check argument from here and subsequently update the call to Template constructor:

inb/inb/linkedin/message/template.py

Lines 90 to 93 in 6341867

	def __init__(
	self: Template, message_template: str,
	*, var_template: str, grammar_check: bool = True,
	use_template: str = None) -> None:

inb/inb/linkedin/connect/linkedinsearchconnect.py

Lines 396 to 399 in 2f66b3a

	template = Template(self._message_template,
	use_template=self._use_template,
	var_template=self._var_template,
	grammar_check=self._grammar_check)

Also, remove the following lines of code from _install() function in inb.sh.

inb/inb.sh

Lines 62 to 89 in c0073b1

	if [ $verbose -eq 0 ]; then
	if [ $EUID -eq 0 ]; then
	sudo apt update
	sudo apt install openjdk-8-jdk openjdk-8-jre

	sudo apt update >/dev/null 2>&1
	sudo apt install openjdk-8-jdk openjdk-8-jre >/dev/null 2>&1
	echo "JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64" >>/etc/environment 2>&1

	else
	echo "Root privileges required to install java!" >&2
	exit 1
	fi
	fi
	source bin/activate
	if [ $verbose -eq 0 ]; then
	python3 -c "import language_tool_python; tool = language_tool_python.LanguageTool('en-US')"
	else
	python3 -c "import language_tool_python; tool = language_tool_python.LanguageTool('en-US')" >/dev/null
	fi
	deactivate

Make sure to update the requirements.txt as well.
