BUG: incorrect handling of line breaks in OdsWriter

[dimastbk]

Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

df = pd.DataFrame(["test\ntest"])
df.to_excel("test.ods")

Issue Description

<table:table-cell office:value-type="string" office:string-value="test&#10;test"><text:p>test
test</text:p></table:table-cell>

I think, this is a bug in ODSWriter, which should convert \n to text:p. Below are files from popular office applications:

• newline_office365.ods
• newline_libreoffice.ods
• newline_google.ods

And handlers in some ods readers:

• https://git.sheetjs.com/sheetjs/sheetjs/src/branch/master/bits/80_parseods.js#L606
• https://github.com/miachm/SODS/blob/master/src/com/github/miachm/sods/OdsReader.java#L502
• https://github.com/ropensci/readODS/blob/7548c3ab8778efc2d6058fc56ca84920b2e3a92f/src/read_ods_internals.cpp#L43

Expected Behavior

Resave example in LibreOffice:

<table:table-cell office:value-type="string"><text:p>test<text:line-break/>test</text:p></table:table-cell>

Create an example in LibreOffice:

<table:table-cell office:value-type="string"><text:p>test</text:p><text:p>test</text:p></table:table-cell>
